Am I overreacting?

I just calmed down after crying because I'm tired. I'm always doing homework or studying for upcoming tests now that teachers need to give us our marks before winter holidays.

But tonight, I guess I'm just too tired due to my lack of sleep or I'm going to explode. In my school we have like "workshops" that are obligatory and are part of the mark, as any other industrial highschool. I'm in Electricity now and this teacher is very strict. Don't get me wrong, that's not my problem.

The teacher gives a lot of homework, and every homework I present it's wrong and I have to re-do it. I'm tired of it. I had to do a whole work in calligraphy tech for him to tell me that I separated syllables wrong (some of them are and some others are well written, but anyways).

This Wednesday, I wasn't able to go to workshop because I was having the worst cramps of my entire existence. In the morning, when they started, I had a physics exam which I did. I was suffering but I mean it, I almost threw up on myself.

I did the test anyway (because I'm a strong girl and some period cramps won't be the death of me), I just had one exercise left but my mom came to pick me up early because I was dying. 

SO, I didn't go to school in the afternoon so I asked for the activities that they did that day. My classmates didn't take a photo of the board. We have a new practical work for Monday. I don't understand a shit of what my classmate told me that we are supposed to do. THEY DIDN'T TAKE A PHOTO OF THE ACTIVITY BECAUSE THEY COULDN'T UNDERSTAND IT. 

I'm mad, tired, whatever is going through me. I'm scared I might not pass all the exams, I cry because of it, because of my mom who would be mad if I don't pass. 

I don't have anyone to tell this things to, nobody gives a damn. I'm suffering, I don't know what to do and I'll die anytime soon. I hope I can talk about this with my mom someday before I really collapse.

I also haven't seen my friends outside school for so long because of all the homework that I have to do. I'm gonna do a sleepover tonight, that's why I'm scared that I might not finish everything that I have to do.

My room is a mess and I don't have time to properly clean it. Picking eberyofrom the floor isn't cleaning, the floor is disgustingly dirty. I feel like a cockroach.

Please give me your opinion on this. And if you have any advice, TELL ME PLEASE I'll collapse.

See you 🩷
