Single mother

I'm 19 and disabled. I have been working on getting social security approved because the father left me and I would have no way to support myself. Lately I've been very fearful that I won't be enough to raise my daughter comfortably in a nice home.. My depression has gotten worse which also scares me. People tell me I should move on and just find someone new. I was wondering if there's any mothers who can give be some insight on being a single parent, or even how they found someone who they trusted to treat their child right.. I'm so paranoid..
