Yaela, that is very, very sad and must have ripped your family to shreds. Every child needs two parents to count on. Every child needs a Mommy and a Daddy. It is extremely sad to not have that in your childhood and your adolescent years when you need them the most. Children need strong role models in their lives. Mothers need their husbands to partner with. It is very difficult to be a single mother whether you are in a marriage or divorced raising children on your own. I am glad that you had a support system to at least understand what was happening and how to handle it. Most kids and families don’t get that. You can’t help an addict. They have a choice to get help or feed their addiction and no one can make that choice for them. The only thing a family member can do is encourage them to get help while at the same time tell them “I love you and that is why I will not stand by and watch you kill yourself. That is not fair to me”. You have to respect yourself too.
The best anyone can do is say “I will support your sobriety but I will NOT support your addiction”.
As far as your food addiction is concerned you might also want to see a therapist and a doctor who can help you with that. It probably has something to do with the need to be loved and turning to food for comfort. A good endocrinologist can help you out by first doing a complete work up to see how your body is functioning and then recommend the proper foods and diet plan, and then a therapist can help you through your issues.
