I wouldnt swap to the injections just for the convenience, you can build antibodies to the medications and you'd kick yourself if changing caused that.
Im at college too. I moved abroad, luckily with my parents so I don't have some daily stresses but I have a whole bunch of others instead.
When I lived in the UK I dropped out of university because of my health mainly, so my best advice is make sure you register at the disability office and make the most of what you're entitled to!
I find it hard and stressful I also find not many understand, my parents especially I often get the "everyone else in college can hold down a a part time job and study! Why can you just make a bit more of an effort" an then I try to explain those are the people who stay up all night cramming before exams n writing papers at 4am my body would have me hospitalized immediately of I even thought that was an option lol
Good luck finding a solution, discuss it with ur insurance n your school you keep nagging n you may get somewhere!
We should def have a college support thread just to keep us all motivated! I find that the hardest when I know I have so far to go before I can get a job that will cover my health care costs!
