Have you thought about applying for Disability Students Allowance? I applied for it based on a few medical conditions I have, two of them being anxiety and depression and they've put a lot of support in place for me. When I start uni in September I'll have a mentor in place to help me deal with being away from home, my feelings etc., that I'll see once a week, if I find it too difficult I may be exempt from doing presentations, etc., etc. It creates a comfortable, supportive feeling, I'm not too worried about people thinking I'm being ridiculous and oversensitive because I actually have DSA to support me and validate my feelings and condition, if that makes any sense.
I hope you have a great time at uni!
