My difficulties with the English

English is a proper noun and as such we don't need to use the article "the" in this case

I am studying English by myself,: no professor, no native speaker and. As such, it is so hard tofor me.

The easiest feed back is that you have to change "to me" to "for me" as english is not doing something "to" you, but rather you are relaying an experience "for" you.

The other is a bit mroe difficult to explain as I am not an english professor haha. But what you have written would be passable in a spoken conversation, but when you introduce these dependant clauses "no professor, no native speaker" it is better to use some sort of connecting word (without a professor or native speaker, for example), or to use a colon (not as common, but impressive to people who like grammar).

I need improve my English, h. He is in the intermediate level.

You should make this two sentences as you have no connection between these two statements (clauses). if you want to connect these ideas, then you could use "because" for example.

I acepptedcept suggestions

simple spelling mistake, no big deal. Then I also changed this into the present tense, based off an assumption. However, "I accepted suggestions" also works if you are trying to speak in the past tense.

My dDifficulties with the English

As previously noted, "difficult" is an adjective, while "difficulty" is a noun.

I am studying English by myself, no professor, nowithout any help from a professor or even a native speaker and. This makes it is so hard tofor me.

This is better expressed as two separate sentences, so I have done the necessary splitting.

I need to improve my English, he is in the to an intermediate level.

This is assuming that it is *you* who wants to reach an "intermediate level"; using "he" would refer to some other person.

I acepptedm open to suggestions.

If you want, you can actually join the last two sentences, like so: "I need to improve my English to an intermediate level, and I am open to (any) suggestions."

You're talking about yourself, so use "I" instead of "He".

"Accepted" is in past tense, which means you have already accepted suggestions in the past.
