Can I sue someone for forcing me to leave my home?

I live in supported accomodation because i have Aspergers Syndrome and ADD and need help with daily living. About 6 weeks ago my support worker, who is also the landlady and owns the building, tried to get money out of me and when i refused, she left and told my social worker I had tried to attack her. After that I wouldn't let her into the flat because I felt I couldn't defend myself if she made a claim like that again. Because the support work is linked in with the tenancy (basically she provides the support or I have to leave) she served 2 months notice on me to vacate the property. I spent a couple of weeks looking for a new flat to move into and found somewhere. My support worker/landlady refused to give a reference, even though I've done nothing wrong and always paid all the rent and bills on time, and the flat is spotless. So the estate agent turned me down for the flat and kept the �75 agents fee. Now i have to be out by friday (5th November), I have nowhere to go because I have no references, and social services are saying they have nowhere for me to move into, so I'm effectively homeless. What can I do about it?
