Sorry to hear that, I lost a few good friends for my life too, it sucks. Obviously therapy is probably the best option but I'm going to stray from that since if you wanted a therapist you wouldnt be on here.

For a lot of guys there is invaluable therapy in just fixing or making things. Its the reason people will buy old sports cars or derelict houses and spend years working on them making them absolutely perfect down to the smallest details. You feel proud at every big accomplishment, you get a break from your problems while you're cranking the wrench, you feel valuable when you created your masterpiece and somebody notices.

A lot of people have different things, like painting, or rebuilding furniture, working on their bodies or whatever. Just keep trying new things until you find something that clicks and you find yourself thinking about your project as you're falling asleep. That's that kind of stuff that keeps a lot of men happy in life.
