Eric, My heart goes out to you. I was that person - who would have stolen just to be able to keep drinking. I loved my family and never meant to disrespect them or cause them pain.
The main thing is that you stop feeling alone with this. You are not a failure - you did what any loving parent would do - you tried to help. (Ok, it's called enabling - but you weren't aware of that at the time.) Have you ever seen the show Intervention? There is some great advice given there - and you will see so many people just like you.
There is hope for your son - he can get well and have a normal life - all the terrible things can be in the past & you can all heal. I hope the Friends & Family forum will help you feel more comfortable with what you are facing. Please let us know how you are doing.
