I haven't totally decided what to study. I'm thinking something healthcare related, so want to do classes in biology/chemistry and then there's mandatory classes in English and maths which should be fun too. As for getting in, I'm more than qualified, the problem is that the closing date is Aug 1st and my master's degree uni hasn't answered my emails asking for them to send my transcript to this uni.
I think not wanting to give in to the triggers sounds like it could be helpful, especially if it helps avoid them triggering you again in the future/doesn't trigger as badly. I really hope that helps.
I don't know if this will help but have you thought about calling/emailing the samaritans if you don't feel able to offload on your friends? What you're going through sounds really tough and bottling everything up inside isn't healthy and might make things more difficult for you.
Jeez, I forgot how bad the NHS can be - that sounds awful! I would say, don't give up trying to get help, I know it can sometimes be very difficult to get doctors to take you seriously (several I saw were total, incompetent *******s), but from what you've said, it definitely sounds like you should be taken seriously and sooner rather than later. I hope you manage to find help somewhere
