Most people turn to drugs or alcohol. Some turn to hookers and kleptomania. I become apathetic. Insanely apathetic.
Yeah, I did alcohol and strippers for the first few months after a few things happened. Still drink, but not too much and mostly with friends having fun, not by myself... Took my mind off things for a bit... Did some other things I never thought I'd do too... Had a few things I religiously believed in, had to break some... Then I went around US instead to see friends I haven't seen in years. Worked great as it kind of took me back in time emotionally. I am now in Portland for about a week, 300+ miles away from my city closing up the debt holes, finishing what I can on the projects that I started before I move on to something new at the end of this month... Feels good to be away, decided not to deal with a few things at this point, leave it for later as they are beyond my control... Slowly getting back to doing shit I feel like I need to do. Took a lot of time to think where I am and where I need to be, adjusted the plans and timelines as I feel would work the best and got a new direction. Most likely will be moving to Sandpoint for a bit soon, closer to home.
Got to the point of trying a few drugs, looked at myself from the side and committed to not do them anymore, also not being around friends who do them for now helps. Tried the ones that would make me work for several days straight, worked once, didn't work the rest of the time... And then I decided, fuck it, if I can't do this without drugs, I'm just going to drop what I do for now... There are a lot of other things I can do well and I will do those for a bit while getting more knowledge on things I do now... Reading and learning new things makes me happy, so I do a lot more of those as well - programming, marketing, psychology, business books mostly.
Basically, like most said, find things that make you happy and do more of those. If you hate what you do, stop doing it for a bit, switch a career, get part time social job, etc., whatever you think you need. There are options. Always. If you can't stop thinking about some shit, learn how to be in control of what you think about. Head is like a can, if you think about garbage, it will become the garbage can and all the garbage you put there will stand on the way of thinking clearly about what you need to do and how to do it. Kind of like GIGO - garbage in, garbage out... Think positively, read things that positively affect you, be around people who positively influence you, etc. Eliminate stress... Sometimes just got to give time for things to sort themselves out. If you can't change something you want to be different, stop thinking how to change it and think about the things you can change... Start with little things.
I didn't go to any therapists, doctors, psychologists, etc... Just read a lot and dropped everything that was stressing me out for a bit. Well, I did read a lot of therapy material online and some books... I still get depressed from time to time, don't follow what I did, just my opinion, I just did what I thought would help me in particular. Had crazy thoughts sometimes, but that's then books helped to get me thinking about something else instead of what I was thinking. I was up to the point where I thought I'd go see a therapist, even got a phone number from a friend just in case. Nothing wrong with seeing one if you have to...
If you believe in Higher Power, pray, meditate, do whatever you think is right for you to make you feel better.
Things get better. Just think clearly. If you need help, ask for help.
Just my 2c.
