Wow, I was in the same boat not too long ago (like a month) I did put the bike on the market, but no takers...which I am glad, because I have rolled through it a bit, feel better and I am working on getting a personal unsecured loan to pay off some other bills/ make things a little easier. I know for a fact if I couldn't ride I would get even more bummed. There are few things that really make me super happy - one - good sex (so far I am not getting much of that these days ) two- my sweet daughter ( whos smiling face lights my world!) three- riding my bike (its just so friggin awesome on so many levels!!)
So, since I don't get the sex, I just hang with my daughter more- she's funny too- and I ride every chance I get. The depression will lift- sorrry the wife is being such a beitch. I work with alot of guys and I am amazed at the stories they tell of their beitchy women. I think if more women had to earn the money and see how hard guys work, they would shut the F up. Its sad.
Hang in there and One step at a time...don't make any rash decisions.
