Funnily enough I used to be a support worker, now I think I'm in need of one! Your MH mentor sounds like someone who I would also benefit from, especially given that yours was also a trained therapist so I can cross my fingers. Dissociating is a problem I have too, or I am hyper aware of everything and everyone around me- instead of listening to the lecturer or my tutor, I am focused solely on how I am sitting, the noises around me, whether or not people are looking at me, what they are thinking about (is it me) etc. It sounds like madness and it probably is, alas I can't help it. I tried getting into secondary care through a GP referral, but they said they couldn't do that. The counselling service needs to refer me, is this correct? It seems like a nightmare trying to get secondary care, psychologists are very hard to access. A few other questions I have for you is, how was your attendance overall? Did your attendance affect your final grade in any way? Did your tutors continuously badger you about why you didn't turn up to seminars or lectures? If they did, how did it make you feel and were they informed to stop?
It's great to hear you stuck it through, it gives me some hope. You are a warrior and you should be proud of yourself!
