Hi riverofdragons
Saw your question a bit late - I know of a mental health 'social inclusion' team in the London borough where I used to work... but maybe no point in telling you what they do now(?)
It's a bit ironic being excluded from the 'social inclusuon' team isn't it!!

How do you mean they say they can't help you? - Why was that? Or do you mean they said they couldn't help you with physical day to day stuff?
You may be able to get that kind of support through Direct Payments (I know people who have), but you'll need to get support with that, e.g. from mental health services (so I'm surprised that the social inclusion team didn't say they could help with that), or you might be able to get support from a disability advice service or an advocacy project, or a local mental health charity....
I don't know where you live. What will be available in each area, with regards getting support with Direct Payments, or other ways of getting support at home, varies around the country.
If you want to say the area you live, I might have better ideas - you can pm me if you'd rather.
I understand your fear of getting used to living on your own, and of getting stuck in the flat - Didn't whoever you spoke to at the social inclusion team give you any ideas about making sure that doesn't happen?

again!
Anyway, sorry you're having a difficult time with it all - come back to me if you think I might be able to help (I used to work for a user-run mental health info project, so may be able to think of ideas about getting advice or support that might help).
Take care
