Have you applied for disability? I ask because it’s better than nothing, but it also probably isn’t going to provide the incentive me you need to get back to supporting yourself independently.
If you still have to call in to your current job, which isn’t 40 hours, perhaps you are no longer able to work full time. It’s good that you have Medicaid in case you get sick, but I am at a loss with suggestions on where to go for the kind of income you would need to provide an apartment and a vehicle.
You can work some while on disability, but again it will not be enough to provide the things you want.
