I relate to your stress, please don't give up. I like Elsa's ideas on housing. I've never had a case manager and don't know how to get one - but that sounds good. Do you have a therapist that can help you find services as to these types of things.

I'd get on the housing waiting list.

It's hard to ask for help, but you're not a bad person for needing it. Reach out to those that can and will help you. I've found local bipolar support groups helpful. Take care.
