Thank you both.
I did ring the local branch of NAS during a recent meltdown. A woman called me back and said there was nothing they could do and to ring the local assessment centre as they could offer help without dx. Obviously they couldn't and suggested I ring NAS. AAARRRRGH!
I am desperately trying to avoid homelessness. I spent many years on the road before, 'running away from myself'. I know I have to stay here in Bristol to get my diagnosis, I am tired of running. I know this is the last battle I have to fight which is a comfort. On discovering my Aspergers I have read lots and my life now makes sense. I think what is the hardest part is the fact I am doing this all alone. It is a very confusing fast moving world at the moment. I would dearly love to meet others who have been through similar.
Accepting that NT's drain me and that I cannot live among them is relatively easy, for it now all makes sense. The difficulty is finding people who truly understand what it is to live with autism. I know they are out there, I am just impatient.
