Hello Jordan!
I'm 23 and was officially diagnosed today but I've definitely been having symptoms for a long time. I can relate a lot to what you say because I've also had to withdraw from school because of my symptoms (and also mental illness symptoms). These past three years, I've repeated the same pattern. I enroll in school for the fall semester, I am really motivated at first and then depression sets in, the pain and fatigue wear me down, anxiety makes me miss classes, and I end up with very inconsistent results because of all that. I used to do very well in school, so this is very hard to deal with. I never made it through a winter semester, not for the past three years.
Online classes sounds like a great idea!
Feel free to message me if you want to talk. I have a tumblr and skype if you prefer. I'm female, but I'm close to your age, and I can definitely relate to some of your experiences. I can imagine being a male with a disease that is usually associated with females makes it even harder to accept and talk about... But your symptoms and struggles are just as valid and important as anyone else's. I hope you'll find what you are looking for!
