Oh Jessica, I am so sorry that you have had to endure such torture as a child, no one deserves to be treated that way, especially children.
I will never walk in your shoes, but I do know a little bit about an abusive parent. My father was an alcoholic and extremely verbally abuse to me and physically abusive to my sister and yet years later she's the one who took him in to live with her and her husband. I wish I could tell you that it will all be alright..but from personal experience..it did not turn out okay. My father kidnapped my neice and ended up in jail and died there.
I too overate as a child and as an adult as comfort from the past. Counselling helped and making the decision to put the past behind me and get on with my life really turned things around for me.
You have been put in an extremely difficult position and you are a compassionate and wonderful person to care for those who hurt you the most. I can't tell you what the right thing to do is...but I do know this...you have a family of your own, and although your parents may not be in a position to abuse you or your family physically, they are already causing you stress and to turn to your old habits again. Your children have a caring Mother and need a healthy one, that's why you got the band.
Jessica, I am sure you don't have a selfish bone in your body, but maybe it's time you think of yourself and your family first and let someone else bare the burden.
Take care sweetie, you know we are all here for you...and anytime you want to talk just send me an PM.
(((Hugs))) Cathy
