One thing at a time. Honestly, if I were you, I wouldn't worry too much
at this point about getting the kids into Alateen or therapy. The best thing you can do for them
right now is get some level footing. Once you are at a place where you can think straight, then look into programs or counseling available for them. They need at least one sane parent, and you're it.
Hugs to you,
