For the last 4 months I have felt like I've been experiencing low mood but thought it would just go away. Unfortunately its only got worse and its got to the point where I'm secluding myself away from my family and friends; it seems that if i'm in their company I only cause an unwanted situation. As the months have gone by I've found I can barely sleep and if I do all I have is constant nightmares. As well as this I'm finding it harder and harder to eat things to the point if I do eat I have made myself sick which has resulted in multiple fainting episodes where I have been taken to hospital and told I may have moderate-severe depression/anorexia/bulemia; this isn't what I wanted to believe but am starting to think they were right. I'm crying everyday, I'm exhausted and extremely stressed; I am at uni and have lost someone I loved but my life has always been quite stressful so I don't see this as a contributing factor. I've got so low in mood that I'm seeing different sides to myself and I can barely handle any social situation without wanting to leave crying. I don't eat, I don't sleep and I can't talk to anyone as much as I've tried. I don't know what this is but I am wondering that if this is depression do i seek medical advice?
