K.A.
I'm so sorry for what you're going through. I can't imagine it's easy with three little ones. Do you belong to a church, your pastor maybe able to help. Also there is Stephen Ministries that runs through churches. You may not be able to go to meetings, but you could try AL-Anon for some references to hotlines. Go to the book store and do some research and find some books there. Good luck and I'll keep you in my prayers.
((hugs))
