I reckon my uni experience is probably up there!
So I originally started uni in 2007. After exactly one (horrible) week there, I took an overdose one night. Ambulance was called, ended up in hospital, intermitted for a year.
Went back (same uni, same course) in 2008. In November 2008, my nan was diagnosed with terminal cancer, and she died in January 2009. I also had major eating problems (to the point of consuming no calories at all for 10 days in a row).
Second year started off better. I had almost no friends at uni due to severe social anxiety (I managed to go into the uni library a grand total of 3 times in my entire degree, and in the entire of my final year of uni I attended 4 lectures/seminars, so I was very isolated). And then in March 2010, not long before my second year exams my wonderful mummy was diagnosed with terminal cancer. I kept my happy act on at home, came back to uni and just completely broke down and went off the rails. The first day I came back after she was diagnosed I went to find my student advisor, and when she wasn't there, I just sat curled in the corner of the stairwell to the offices and just sobbed my heart out. I ended up detained under s.136 Mental Health Act by the police 6 times within 3 months (3 times within the space of a week during my exams, where I missed one exam due to being sectioned, and went to another exam about 5 hours after being discharged from section). Went back in my third year and I ended up in a psych ward for 3 days after being 136ed again, and then moved home. Spent my third year of uni living back at home, teaching myself the course material from books and online, and just being with my mum while she went through treatment. Graduated in July 2011 (with a First and a Final Year Prize, which I am stupidly proud of), and my mum died 4 weeks later.
Had two years out and then went to do my MSc at another uni. Which was the best uni ever for me, so much smaller and such a nice atmosphere, actually developing a rapport with the lecturers, and with the help of the lecturer who taught us for our first two modules, he helped me to build up to actually managing to whisper a couple of words out loud, to communicating my thoughts via e-mail, and actually speaking to him. 100% attendance, 75-80% in all assignments, and I just loved my MSc course.
Only I also developed severe anorexia nervosa, and in the space from July 2013 to April 2014, deterioriated so much that uni finally convinced me to take 6 months out, on the basis that they were veering towards taking it out of my hands because they couldn't watch me deteriorating like that anymore, so spent 5 months inpatient, went back to uni the week after I was discharged in September (and then had a pretty awful relapse, a suicide attempt and 3 months of attending day hospital twice a week), before finally finishing and graduating in October (2015).
Pretty horrific few years tbh! But I absolutely love my MSc uni, and I loved my course, and I am so glad I did it, have made so so so much progress.
