Mr Orange

I have an ex girlfriend whom im still very close to, she has been suffering from depression for over 2 years, was on medication but she's stopped it as they made her feel funny. she doesnt talk to councillers when her parents take her to them.
Her current bf is a total control freaking cunt of a guy and has stopped her talking to most of her mates, hes contantly arguing with her as he hates and i mean truely hates her talking to me.
any pointers so i can help/be a shouler to cry/comfort on??
ill be honest and say im beside myself with worrying about her,
Pm me if you want to, im not fussed, im just looking for pointers to help her through what must be a living hell
