I am asking for help not for myself personally, but for my boyfriend. We've been together for two years and he is my best friend and I love him so much. It makes me really worried and sad when he shuts off and goes silent for days when he is having a depressive episode. I don't know what to do. 

He used to be the sunniest, goofiest person. He has the best laugh and can be so infectiously happy when it's the two of us together. And I love that so much about him. He makes me so happy. I feel like I can imagine my whole life with him. Laughing every day. He can make even boring chores like folding laundry or cooking the most interesting activities. 

He struggles a lot with depression. I am no stranger to mental health issues, but I don't have depression. I don't know how to be helpful or to make him feel better; and I end up beating myself up with insecurity and worry when he gets that way.  I am worried that this is going to be the rest of my life, a few good days and then abrupt coldness where there is nothing I can do to make the situation better. I am worried about him not finishing school, or going to work. Or one day I will come home and he isn't there anymore. 

My dad has depression and recently he overdosed and had to go to the hospital. It was the scariest night of my life and sometimes I wonder if it would ever play out again but with my boyfriend. It's terrible to think about but I can't ignore the thoughts. 

I have mentioned a therapist to him before; I regularly see one and it's done wonders for me, but he doesn't think that it would help him because he says its the world that makes him feel the way he does. Basically he'll say he has no hope for his future, and when I say that maybe a therapist could help him sort through those feelings he tells me, "Unless the therapist can solve every problem in the world then I don't think so." 

So now I am desperate and asking the internet for help. I just need advice on how to help him, if I can at all.  There is a small part of me wondering if I should break up with him, but the thought of giving up on my best friend in the whole world makes me want to cry,
