"Today was a terrible day because..."

[Caunadan]

Thank you for your advice, Pineweaver Pichu. Sorry to hear that you struggled in language classes as well. :/
Perhaps I should write a quick update about the situation : I'm still struggling with the English class, I can't talk with the teacher after the class because she always leaves the classroom quickly after the class, and she did not reply to my email.
I discussed the situation with my only college friend (he is not my classmate, but he has the same English teacher as me). He gave me some advice, which is very nice of him, but I have not been able to get feedback about it from the teacher yet. After all, students can make mistakes, even if they have good intentions.
As for someone who can help proofread my work before I submit it, that's not exactly the person I'm looking for, because most assignments and tests for the English class (including the final exam) must be submitted orally.
I confirm that it is hard to keep my confidence in this situation, especially as a PXR member : I hope that no one on this English-speaking forum will judge me because I'm struggling with the English class.
Last but not least, thank you for your support. That's very kind of you. :)

I don't think you have to worry about anybody judging you over it here; I sure won't. Orally is one thing and it's understandable to me how a non-native speaker might struggle if that's the format, however when it comes to your writing/typing, on here and online in general, your English is very good! If I had not known otherwise and only knew of you from the things you've typed here I would not have guessed it was not your native tongue. Wish you the best with your class and oral report struggles (and I think you should continue to try and speak to your professor about it, perhaps even leave a note on her desk at the start of class one day or something asking her to see you for a minute when it's finished and before she leaves quickly, if she doesn't get to e-mail) but I wouldn't worry about any judgements from people here, I can't imagine anybody here being like that.

Being monolingual and always having struggled greatly to learn any new language apart from a few words and maybe phrases, I've got respect for anybody who is as adept at more than one as you demonstrate. :)
