I'm not really a "silver linings" kind of guy, but I do think you could look at things differently, perhaps.
Be grateful you're no longer in a relationship that cripples you financially. Your shitty job that doesn't want to give you the hours you need can now pave the way for a better job that's a better fit for you. And you can now build really special relationships with the 10% of friends who truly see your value.
I feel mostly despair these days. Sometimes, it's nice if people can remind you that there is hope. It's really difficult to spot that hope when you're in such despair, though. That's where others come in.
I hope you find some peace of mind eventually, however that comes.
