I can't do SHIT

Idk I have a lot of illnesses. I take medication for anxiety and depression, so I can't really drink. That's a normal thing almost everyone can do, meanwhile I'm never going to be able to get drunk and do some shit I'm definitely going to regret later. Nobody likes doing it but it's a part of life everyone's supposed to experience. Not me! I also am suspected for hEDS so god knows what I'm supposed to even do with that anymore? I can't sit normally because it's uncomfortable but I can't sit any other way because it makes everyone else uncomfortable, I can't raise my hand in class without struggling to breathe and getting dizzy and almost passing out, I can't walk up a set of stairs without my knees creaking and popping, I can't be normal in class or have normal friends because everyone thinks what I can do is "gross" or "cool" or both but nobody thinks it's an actual issue! I had to go to the school nurse almost every day when I was younger, she knew my name and the things that went on in my life we were practically best friends because I was almost constantly with a headache or with nausea or I felt dizzy or whatever else. I'm so irritated because I literally can't do shit. I want to do normal human things. Why can't I just be normal it's all I've ever wanted. But the universe is conspiring against me like a group of evil teachers all assigning homework on the day of a school event you really can't miss. This is bullshit I just want to do things. Normal things. I'm so pissed off.
