I want to tell someone

This past April, I had a period where I couldn't sleep due to hyperventilation. I think it's a culmination of various things that have happened. But today, I want to write here about the one thing I can't forget and am suffering from the most. I suspect I wouldn't be understood if I told someone directly, so I'm writing it here. I'll write what I'm thinking now, so please excuse me if my writing is poor. I'm a student and also in the student council, so my days were fulfilling. However, around the beginning of April, suddenly when I tried to sleep, my heart would hurt and I'd have trouble breathing for several days. Still, I went to school without paying much mind to it. But one time, there was a club activity tournament. The night before, my heart hurt terribly, and it was so difficult I couldn't breathe, so I couldn't sleep at all and ended up missing the tournament. Then, when I went to school on Monday, my advisor told me, "If it's too hard, you can quit." I knew I had been going to club activities intermittently and causing trouble, and when they said that, I thought I could finally quit. But gradually, for some reason, those words started to sound like, "You're useless." That would flash back at night, and around that time, I started experiencing hyperventilation. I actually want to write more, but I'll stop here due to character limits.
