I have to recommend for you to do 2 things. First I would set up an appointment to see a psychiatrist. This would be to see if they can help you deal or manage your problem with being claustrophobic. The next thing that I suggest if you have not already tried it is to try using a nature sleep aid. You can go into any grocery store that has a vitamins section. The one I recommend is called Melatonin. I believe once your are able to deal with being claustrophobic the rest of your issues will go away. I hope this helps.
Unfortunately, the school's caunseling unit wasn't agreed to arrange a psychiatrist visit for me . And now, I think that it has been far too late as I'm passing the deadline . So , I'll just be prepared to be kicked out of this school, leaving all my research , oh goshh , they wouldn't realise on how crucial the research is . I didn't do it for myself, it's for my mom who suffer from a very rare kind of cancer and I'm pretty sure that I'm very close to the answer , so is the mentor panel . After all, it's the administrator's decision , and thanks for your recommendation , I'd appreciate that . :)
I so feel for you. I think anxiety from your mother's poor health and other stresses may be causing psychological problems. If you can't get to a psychiatrist, go to a family doctor. They can prescribe psych meds short term and refer you to a psychiatrist. It usually is quite a wait to get in to a psychiatrist. You need to get to a doctor ASAP! Also, maybe you do need a break from this high-stress school. You are so young, you have plenty of time to take a break and then find something else that fits you better. I'm in my 50's and am going back to school for a career change! You have tons of time!
