How can I help my depressed boyfriend please?

my boyfriend is in trauma now, because he is shocked of my past, I tried to hide it from him, and then I told him my stories and according to him that it's not the stories but also the way I've told them, and he went to the hospital 13 times so far, and goes to see a psychologist and therapist and he says nothing is making him feel any better and this shock is so hard and now he has deep depression and take lots of medicines, the problem is he loves me a lot and according to him now he cant be with me and can't be without me, and we work in the same office as well, and we have to deal with each other every day, and we can't change this at least for another 2 years, and every time he sees me he get more depressed, I don't know what to do or how to deal with him, I love him and he loves me but we can't be together and I really want him to feel better, his psychologist said that now he has a chronic depression after this shock, what can I do to make him feel better and to make him happy again? I need a real honest help here, he tried to kill him self , & I don’t know what to do?
