Thank you for all of your responses, they are helping me to begin to put things into perspective.

The situation with my boyfriend is not salvageable, he has cut himself off emotionally from me. It's almost like talking to a different person, it's so heart-breaking. He could not handle seeing me upset and could no longer feel he could trust me to get help, although he does admit that he didn't encourage me enough to seek help. He is prone to depression himself, and although he understands what it feels like which helped me initially, his coping strategy involves ignoring his feelings and keeping himself busy until the emotions fade, a tactic which never would work with me.
Although he is willing for us to talk, he has made it clear that we can only ever be friends as he will not put himself in the position he was in again. I completely respect and understand his decision. I couldn't put him through it again.

I will continue with my meds and seek therapy/counselling. There is a problem, but I know that I don't want to waste my life.
The more I realise that I desperately want to feel good about myself. I feel selfish and self-centred to even say so, thank goodness it's anonymous... How can I do this?
