if you are a council tenant, get onto their website pronto.
(have no idea about housing associations, sorry)
the sooner you tell them about your circumstances, the sooner they can advise you.
Am so sorry to read of your issues, make a cup of very strong tea/coffee and have a damned good cry xxx
Do hope all works out ok for you, there are loads of helpful people on here who can steer you to various web-sites for assistance
