I've read posts on this thread and come close to posting a few times, but here goes.
I've always been crap at keeping in touch with people, its not that I don't like them I just enjoy my own company and get wrapped up in things. According to one friend this is a "personality disorder", to me its just me, probably live too much for today.
After splitting from my wife I ended up in a bad place, a company that enforced working from home for long periods didn't help. I spent far too much time planning which would be the "best" way to go. One night I found myself on spitfire bridge over the M3 watching traffic go by, luckily a woman stopped and spent some time talking to me. She basically saved my life and I'm ashamed to admit I never asked her full name or address. What mainly pulled me out was having a friend with bipolar, whom became very dependant on me, and thinking of my sons. To be be perfectly honest finding a friend with benefits probably was also a help
Now I'm engaged, new career and looking forward to life.
My eldest son has depression and it is very hard for all of us, not knowing how to help him and seeing him suffer. I think for family feeling so helpless and knowing that the person you love is suffering is awful.
