Sweetpea -
No. You do not want to let your family go. That will be a huge mistake only sending you into a worst situation.....all alone.
When is the last time you considered talking to your DR.? And have you considered something like Antabuse?
I know there are other solutions and more importantly, I know your family will support you if you explore them with their help.
You are not worthless, you are important and I know I love getting on MWO and checking out the Sweetpea express.
If you want to chat, let me know....or better yet, I can even Skype you so we can chat "over the pond". I'm here and would love to talk with you so there's another indicator of just how important you are!!!!! (Hey, I don't just chat with just anybody!!!)
Stay strong.....you are important and so is your family.
Hugs, Erin
