<human>: I haven't been dating my boyfriend for very long - it's only been about 4 months. He already been displaying neediness, which I understand completely and I reciprocate. But lately, he's decided to quit smoking marijuana (which he does every few months and begins again). One day, he will say that he is glad he decided to quit, and the next he will fall into a grandiose depression. Unfortunately, even before he quit, he would still get extremely depressed.

A few days ago, I was out of reach and he left me very startling messages on my facebook. Paragraphs written about how he was about to hit rock bottom but how he knows he needs to stay strong for me. I keep telling him that I am here to support him and encourage him to get help but I feel like this is not enough.

His father died when he was 17 (he is now 22). He suffered from post-traumatic stress disorder afterwards and saw a therapist. He has a history of depression and addiction in his family.  What can I do?

Give me a shortened version of the text
