What should I do about my depressed bf?

I too suffer from depression (bi-polar). Years ago I learned to cope with it and keep it in check. Today I no longer use meds (although that doesn't mean I'm cured - there is no cure). It takes a strong individual to understand what makes you fall down. But that is for a different topic. In the case of your bf, certain things can trip it off. Most of the time it is something usually small. Most likely - you may have noticed (maybe) that he also has a loss of appetite as well. This is a dangerous circle. What I have found over the years is that when you stop eating (as most depressed people sometimes do, I know I did, was always trying to starve myself), you become MORE depressed and the situation worsens. The then causes lack of sleep because your mind is torturing yourself (remember - your mind is your worse enemy). The reason that this happens in most people is because you deprive your brain of "chemical's" (to keep it simple - as in the case with me, lithium). And when that happens, you get more depressed and less hungry. Get the idea. From personal experience here are a few things to try - may or may not work but for YOU it really helps him (he won't know it in his state of mind) - fix him something he likes. Have to get the appetite up. Once that starts you'll see a small improvement. With guys - we're pig headed - so "mothering" him to see the doc won't work. He will go with in time. The harder you pull the more he'll push. Its just nature. Unlike girls - most guys don't like to "talk" about their problems(we're fixers heheh). So instead - without crowding - start small and do simple things with him. Find out what makes his depression kick in and then find things to do that avoid those situations - might be a song, movie, someone IN THE movie, a smell, places etc. You get the idea. Sounds like you love him. So you'll know what works- its good he has someone like you by his side seeking an answer - its helps more than you know. And with in time he'll be back at his counselor (ps - never use the word "doctor" or "help" to us depressed people it brings up very bad images and makes us run)

He probably doesn't want to see the doctor anymore because itz not helping him.
Does he read books? You can suggest some self improvement books?
Or if you know what makes him happy, then you can try doing those things for him/with him. Like for example, if you know he is into basketball, then play with him, or encourage him to join a team.
Or maybe introduce him to the game WOW. - guys love it.
We all have some kind of interest that takes our mind off "life". so try to get him to DO whatever it is.
Also, maybe you can try looking up volunteer programs, where you and him can help the community. Maybe play with orphans, or help the poor. Or get involved in a church group. Sometimes focusing on other people can take away our focus on our miserable life, and seeing that we can make a difference in other people's lives, can make us feel better about ourselves.
Dont let him sit around, doing nothing, because all he will do is think about how miserable he is.
You have to get him out there and show him whatels life has to offer.
