my wife is suffering with bad depression after we had to move

hi there my wife is suffering with bad depression after we had to move to another town as our old flat was going on the market. she has Asperger syndrome and ocd ,ever since then her mood has been so low that she is always saying she wishes she was dead. i love her so much but i dont know what to do or say anymore nothing i say to her helps shes trying to self harm again and its not that i havent tried the doctors but they haven't really done a thing to help her not really. i wish i could afford some private counselling for her but as we are on UC and her PIP we cant really afford it. i really dont know where else to turn to its so distressing watching the women i love like this. any help will be gratefully received
