They say when something like this happens, the most important thing you can do is talk about it. Well it sounds like you're talking about it. I think, because you mentioned so many problems in your life, this is the time to sit down and make gratitude list. Think about all the things that you are truly happy about. In times like these, it's easy for us to get sidetracked with all the bad crap in our life, but there still must also be a lot of good. Keep your head up bro, this too shall pass.
PM me if you need to talk.
