I don't know how to write the tittle better in order to express my feeling.

I hope through the text you can figure out what I am trying to say.

Since high-school I became aware of (the feeling of / my) shame.

Shame as a concept can be very broad, from shame that you feel internally to the shame from other people. It is good to specify.

As I experienced many failures, (regarding / relating to) love, subjects (school subjects?) , etc.

'regarding to' is not really used, you just need 'regarding (thing).' Otherwise you can use 'relating to'
I think you meant "other subjects" aka other things aside from just love

I realized how strong it was, how wit could cause a pain as big(deep / potent ) as if your skin was burning.

'big' is usually used for physical sizes

'could' = potential to hurt this bad. 'would' implies it hurts this much every time

Since then I started working so hard in order to avoid shame, (whether it be/ such as) the shame of failing, mistaking, lo mistakes, or losing.

Must connect "the shame of.." to sentence using conjunction

loosing = not being as tight, losing = failing

Mistaking usually means having the wrong idea (e.g. mistaking a lion for a tiger) . For a more general use, 'making mistakes' work

High school was for me onsome of the best years of my life, even though I was constantly working so hard just forto not feeling ashamed.

High school is multiple years, so 'one' does not work

But by(during that time / back then) I did not realize that.

In order to avoid shame, I've been working so hard, which has lead me to certain positive things such as: getting in a good Uuniversity and getting a job.

"Why aAfter I succeeding, why are my emotions are not aso strong as when I failed?"

Don't use 'so strong as', use 'as strong as'

and that's because I work so hard not for praisinge but for avoiding the shame of "you are supposed to know that", "that was really not difficult to do", "you're clever thenso why did you fail".

praise = noun compared to praising = act

The same goes infor love.

Feeling ashamed is natural every now and then but I do not think it's something to find motivation infrom.

I feel happy where I am, but at the same time I feel like "it's the minimum you could do".

My bBiggest mMotivation is: s Shame

I don't know how to write the tittle better in order to express my feelings.

That's okay! We're here to help.

In English, when we refer to our own feelings, it's always plural.

I hope through the textwriting you can figure out what I am trying to say.

or,

I hope by writing you can figure out what I am trying to say.

Since high- school I became've been aware of shame.

or

I've been aware of shame since since high school.

As I experienced many failures, regarding to love, school subjects, etc., I realized how strong it was, how so much pain can feel as if your skin were burning.

This is a very beautiful sentence.

I don't think failing in love is something about which to be ashamed. Sure, it hurts and is frustrating and disappointing but please try to avoid feeling shame because of it.

I realized how strong it was, how would cause a pain as big as if your skin was burning.

This was an incomplete sentence so I deleted it and added it to the previous line.

Since then I started working so hard in order to avoid shame, the shame of failing, making mistakinges, loosing.

I find this heartbreaking.

High school was for me onsome of the best years of my life, even though I was constantly working so hard just for notto avoid feeling ashamed.

"Years" is plural so I replaced "one" with "some."

But by that time I did not realize that.

This is an incomplete sentence so I deleted it and added it to the next line.

IBut at that time I did not realize that in order to avoid shame, I'ved been working so hard, which hasthen lead me to certain positive things such as: getting into a good University and getting a job.

Congratulations!"

This is past tense so I changed it to "I'd been working so hard ..."

"Why after I succeed my emotions re my emotions after I succeed not as strong as when I fail?," and that's because I work so hared not so strong as when Ifor receiving praise but for avoiding the shame of "you are supposed to know that," "that was really not difficult to do," "you're clever so then why did you fail?"

This is a normal part of the human condition. Practicing gratitude really helps to counter this.

and that's because I work so hard not for praising but for avoiding the shame of "you are supposed to know that", "that was really not difficult to do", "you're clever then why did you fail".

This is another sentence fragment.

The same goes infor love.

I cannot takebe in a relationship in which I do not feel likeas if I am winning.

Whoa!

"Be in a relationship" is the phrase we use in the US.

Feeling ashamed is natural every now and then but I do not think it is something in which to find motivation in.

I agree.

I feel happy where I am, but at the same time I feel like, "Is this the minimum that you couldan do?".

My biggest motivation is: shame

If you use "since", you have to use present tense.

My bBiggest mMotivation is: s Shame

You don't need the semicolon there since you have 'is.' If you do want it, rephrase the title to: "My Biggest Motivation: Shame."

I don't know how to write/phrase the tittle to better in order to express my feelings.

Since high- school, I became (more) aware of shame...

I feel like adding 'more' would be accurate unless you really did not feel shame at all until high school. Connect this sentence to the next one

A...as I experienced many failures, regarding to love, school (subjects), etc.

I realized how strong it was, how would cause a pain as big; it was as if myour skin was burning in pain.

You don't need to use 'as if' if you want a stronger metaphorical effect. See here: "I realized how strong it was, how my skin would burn in pain."

Since then, I started working so hard in order to avoid shame,: the shame of failing, mistaking, loosing(and) losing (etc).

Choose 'and' or 'etc' depending on your intentions.

High school was, for me, one of the best years of my life, even though I was constantly working so hard just forto not feeling ashamed.

But byat that time I did not realize that...

Connect this sentence to the next one.

I...in order to avoid shame, I've been working sovery hard, which has leading me to certain positive thingoutcomes such as: getting into a good University and getting a job.

So, I was thinking,...

continue to next sentence

..."Why after I succeed my emotions are not so strong asdo I not feel as strongly when I succeed compared to when I fail?"

and tThat's because I work so hard not for praisinge but for avoiding the shame of "you are supposed to know that"," "that was really not that difficult to do", "," "if you're clever then why did you fail"."

Feeling ashamed is natural every now and then, but I do not think is something to find motivation in.

I feel happy where I am, but at the same time I feel like "is the minimumthink to myself, "is this really all you couldan do?".
