One of my problem is I'm haven't person to speak with him on his native language.

One of my problems is that I'm the only one who talks to him in his native language.

I don't know, have I need to speaking, but it's would be helpful.

I don't know, if i have to speak, but it would be helpful

I do exercises and writing dairy on English every day.

I do exercises and write dairy in english everyday

I didn't write big texts on this language until that day, because I was afraid of mistakes.

I haven't written long texts in English, because i was afraid of making mistakes.

My studing(?)es

I have started to learn English again.

Using the present continuous tense ''I'm starting'' suggests that your studies are in progress. The simple present tense ''I start'' implies you have a habit of starting to learn English.

I was learning the English language at school, but it's nothing to give meI didn't enjoy it.

''but it's nothing to give me.'' Do you mean you didn't enjoy it?

One of my problems is I'mthat I haven't person to speak with him on hisspoken to an English person in their native language.

Some grammatical errors here. The pronoun ''their'' is useful if you don't the gender of the person.

On the other side I'm learning English toby watching movies orand reading books.

'On the other side' Suggests you are building an argument.
Careful with conjunctions and prepositions.

I don't know, have: do I need to speaking, but it's English? It would be helpful.

Use punctuation to break up ideas. ''Have I need'' is better expressed ''Do I need''. You need the infinitive ''To speak'' rather than the continuous ''speaking'''. I added ''English'' otherwise you are asking if you need to speak at all, in any language.

I do exercises and writinge in my dairy oin English every day.

Again, careful with prepositions and work on your understanding of when to use the base or infinitive rather than the continuous forms of verbs.

I didn't write big texts oin this language until that darecently, because I was afraid ofto make mistakes.

'That day' is not incorrect grammatically, but it suggests that there was a certain day when something happened that changed your habits, and you have not mentioned this day.

I don't know what ielse I can write else.

So, it's the end.

My studying(?)

As a general rule "ing" is added to the end of a word without dropping any letters.

I have started to learn English again.

Or you could say "I am starting to learn English again."
"I have started" is past tense, "I am starting" is present tense.

I was learning English language at school, but it's nothing to give me gave me nothing.

The word "language" is not needed in the sentence for it to make sense, but "the" is needed if you do. "I was learning the English language"
The first part of the sentence is in the past tense, so the second part needs to be in the past tense too.

One of my problems is I'm haven't got a person to speak with him oin his native language.

"am" is not needed when using "have". When saying "I haven't" "got" is needed, or you could say "I do not have a person".

On the other sidehand, I'm learning English to watching movies or reading books.

"On the other hand" is normally what is said.
"to watch" doesn't need "ing".

I don't know, have if I need to speaking, but it's would be helpful.

I do exercises and writing daie a diary oin English every day.

"ing" is not needed.
"dairy" and "diary" are easy words to mix up when writing.

I didn't write bilong texts oin this language until that day, because I was afraid of mistakes.

Because you are talking about the length "long" is used.
"until that day" is not wrong, but you haven't said what day you are talking about. Do you mean "before" or "today"?

I don't know what ielse I can write else.

So it's the end.
