I don't know you, but I know your situation, I've been there. God bless and heal, as only you can do. Give Strength, Joy, and Peace to this family, whom are your children.
Amen

Philippians 4:13
I can do anything through Christ, who strengthens me

Flossy,
Don't give up!! God Loves You, you are listening to the wrong voice, the one of the deceiver. Satan loves to imitate the God voice to steal your strength and your goodness and eventually your Soul. Don't let that happen, check yourself into rehab to clear your mind and body. God Doesn't Make Junk!!! You are loveable, get on your knees and pray for his forgiveness and strength, he will carry you when you are not able!! ;-)
