I wanted to second the advice to Try your GP.
After 13 years of coping as a single parent with 2 kids, one ASD etc, and a SERIOUSLY unsupportive ex, crap family support, useless professional support ETC ETC.. I had a breakdown last year and went on AD's, and it really was the best thing I culd have done. Life now is just the same, eg no easier!, but the AD's seem to have given me a bit more of a 'forcefield' to protect myself from folding in a heap at the bottom of a bottle of vodka.
Really hope you're OK, you've had good advice here from everyone, hope it helps you
