I understand your present circumstances, Canuck, and it's a very nasty place to be.
Quitting alcohol made me much better, but it did not bring full relief from my General Anxiety Disorder and Depression, I see a psychiatrist for those problems and have periodic therapy from an addiction specialist. Your anxiety and depressive thoughts may be situational or not, but it doesn't hurt to be seen about it by a professional, either way. Consider if you were feeling this way before you were drinking or as a result of it.
In any case, the booze is going to fuel the bad emotional states greatly.
