Just sum situation

Basically I had a very rough day, I think, actually no, but it was overwhelming for a moment. It was like a snowball growing today of different challenges that might seem normal but for me, they aren't. I think it all started when me and ny classmates had to bring chairs and tables upstairs, honestly? I didn't do shi, just a little. The first floor was crowded, there was too much people, too much things, I think I couldn't be able to pass through the people as the space was small. I went with some classmates to a room, to chill idk, I didn't spoke to em either because they weren't my friends plus I don't speak the same language, in that room I felt nervous too, I felt I was doing nothing, I felt a lot of pressure, I felt they were looking at me or that by my presence I was making the uncomfortable. Anyways, I went downstairs to help again, and I felt bad again as I didn't know how to grab a table, again, too much people, I was sweating, everyone was I think so and that also made me feel uncomfortable. Some people had to help me because I didn't know how to move the table. I also felt bad because out of nowhere or because I wanted to help I interrupted some classmates to their way to put chairs and yeah. The other hour it was just my classmates playing, I had a headache. And in the other hour, I was without energy, I sat besides a friend, the teacher was explaining me something but my mind always darted off, and it was harder because it was another language. A friend tried to help me with some AI, but I wanted to like understand what I was reading so I was slow, but like she told me to write, but I still was slow, I was js feeling a lot of pressure as I also felt she was looking at me like "do it" zamn, also, she was like doing noises with the pen to signal that I write, but that noise was just so annoying that I just asked permission to go to the bathroom to get fresh air or just breathe. I now feel bad, because I think my friend took it bad or that I'm bad, like, I was stressed and so, I couldn't handle it more, and well, I don't know, I'm just feeling anxious about it. Just that, wanted to vent here
