Hello,

I'm 20 and I can relate almost entirely to you. you are definitely not alone in losing sleep (hence the late night posting spree I've been on) and yes, it is bad not sleeping. Not meaning to frighten you, but it has been said that not sleeping can reduce your immune system. Not sure if that's true, but i always try to sleep just in case.
I always feel *s if I don't sleep well, my stomach feels icky and acidy, so that's probably why you're feeling a bit unwell at the moment. I understand about not wanting to sleep at friends, but don't let it stop you going anyway. You could stay till late at night, then get a lift home? or you could just go for it? If you have taken hand washing precautions all day, then you will be fine.

Also, I almost didn't apply for university, but I forced myself to, and it was the best decision I ever made. Yes people do get *s after alcohol, and yes you will have to share a bathroom and kitchen etc, but I am in my second year now and live with 6 others, and only now has 1 person gotten a *sv.
I am much better with my emet thanks to uni, it made me stronger and more resilient, though I do still worry endlessly i don't let emet stop me from eating and doing things I wants to do. You will be fine, you probably have a muuuch better hygiene routine than most others simply because you are so aware of germs, which makes you a lot less likely to pick things up.

Good luck! xx
