I feel how you do! I suspect i'm bipolar but have no evidence- just how I feel. I used to self harm excessively in my early teens and I also have problems around food. I never have been interested in it and find myself always watching my wieght- even tho people say i'm thin. I have recently put on a bit of weight. I have noticed also, in my 'high moods' I eat a lot and when i feel down, I feel I don't want to, can;t be bothered, too stressed to eat....
There is nothing wrong with going to the doctors and if at worst you are diagnosed with it, you have to look at it like that was always the case. You may aswel be helping your condition than living in denial. Surely that will effect you studying being a nurse more severely!!
