I don't know who to talk to

I'm out off work with significant colonic disease. I had an endoscopy and they found problems in my stomach that explains why I keep vomiting every day. 

I''m living at my mother's house, but she wants me out.

I phoned CAB and they said they can't help me unless my case is special regarding housing.

I visited CAB by appointment a few years ago about a different issue and tried to explain my issues. Afterwards, when I say bye and walked away, she called me a 'f**king idiot' under her breath. She didn't know I was undiagnosed.

It put me offf getting help. 

My dream is to just live alone and have a garden, but that obviously isn't going to happen.

I wish I could find a way to do this. 

I can't socialise and I can't take loud noises.
