Jacquie,
I wish I had some answers for you, I truly do as I am in much the same situation as you.
I won't go in to the long version just know I have 3 grown children and all 3 have been suicidal and I could go on and on, I have to say I know I let them take advantage of me and by doing so I'm not doing them any good either, so please if you should find such a group as your looking for pass it along!!
Please know your in my thoughts and if I should find anything to help I too will pass it along.
Hugs, LindaM(suede)
