So it has been a lot of things have happened in my life lately.

I am doing an internship in construction area as an architecture student.

You don't need to say area because it is implied when you simply say "construction". But you could also say "in the field of construction" if you wanted.

After this construction internship, I need to completed one more internship to be graduate.

"to graduate" or "to be able to graduate"

In fact, I am afraid to be graduate.

"afraid to graduate" -> as in, the concept of graduating OR
"afraid to be a graduate" -> if you want to specifically refer to the noun/person of being a graduate

It is weird to share those things with total strangers, but also easy.

So, thank you for listening to my whinings.

I have a mixed feelings about the internships (that) I am doing right now.

No one cares about me or what I am doing.

ToIt is my understand,ing that most of the interns didn't come during their terms and they are not used beto having an intern around them.

The first part of this sentence is still a little hard to understand in my opinion.

One of the former interns and now newly architect made something for them inon the computer.

To be honest, I wanted to be in the area,field to see what construction workers what they were doing.

My correction implies you wanted to be in "the field", which is the natural environment where construction workers work, as in you wanted hands-on experience to see what they do. You could also say "this field" if you are talking more generally about the the subject of construction.

I mean, I am pretty good at architectrural programs [until my laptop can take in.]

In the bracketed [] section I do not understand what you meant.

But I don't want to edit tohe supposed -to -be finnished project.

This sentence is also a little unclear.

Those things really need a enourmous man power.

I don't like to speak, so trying to speak with them draining tos me.

I couldn't find the questions to ask them.

Sometimes, JI just I watched them without speaking.

In fact, I becoame very friendly towards them.

I think, some of them geot bored of me to watching them.

Everyone askings me that why I choosed to be an architect.

Just,It's just because I like to drawing.

That was the only reason to 18 -years teenager-old me.

Internship in Construction Area

This sounds a little bit like your internship is specifically on a construction site/zone. If that's what you are meaning to say, then this is fine.

Otherwise, I would probably phrase this as "Internship in the Construction Industry" or "Construction Internship" for clarity

So it has been aA lot of things have happened in my life lately.

I am doing an internship in construction area as an architecture student.

I would probably come across it written this way instead.

After this construction internship, I need to completed one more internship to be graduate.

to graduate = the act of graduating from university
to be a graduate = to be a degree-holder

You wouldn't see "to be graduate"

In fact, I am afraid to be graduate.

So, thank you for listening my whiningsto me complain.

Alternatively: "So, thank you for listening to me whine" although this is a little unnatural, whining makes me think of a child and I don't think that's the imagery you're going for.

I am unfamiliar with "whinings."

I have a mixed feelings about the internships that I am doing right now.

From what I can tell from the rest of this piece I think you are only participating in one internship.

No one cares about me what I am doing.

To my understanding, most of the interns didn't come during their term and they are not used beto having an intern around them.

Alternatively: "From what I understand,"

One of the former intern s (and now a newly architect) made something for them inon the computer.

To be honest, I wanted to be in the area, to see what the construction workers what they were doing.

I mean, I am pretty good at architectrural programs until my laptop can take in.

I'm not sure what you are trying to say with "until my laptop can take in"

But I don't want to edit towhat's supposed to be a finnished project.

I think this is the meaning you are trying to convey.

I try to understand howwhat they are doing.

I try to understand how they are doing = I try to understand how they are feeling emotionally

I try to understand what they are doing = I try to understand what actions they are taking

I try to understand how they are building the project = I try to understand why they are making certain decisions

I think you meant to use "what" here

Those things really need a enourmous man power.

Alternatively: "These projects require enormous manpower."

I don't like to speak, so trying to speak with them is draining to me.

I couldn't find thean't think of questions to ask them.

I corrected this to present tense for continuity.

Sometimes, JI just I watched without speaking.

present tense for continuity

In fact, I have become very friendly towards them.

"become" doesn't make sense in the original sentence

"have become" implies that you have developed a relationship with them over the time you've been at this internship

I think, some of them get bored me toof me watching them.

Everyone askings me that why I choosed to be an architect.

"to choose" is an irregular verb, the past tense is "chose"

Just, II just like to drawing.

That was the only reason tofor 18 -years-old teenager me.
