After years of relapsing, my parents are pretty much over me. They were over me the first time they found out I was an alcoholic. Sometimes people just don't understand when they haven't been in your shoes. I suggest you ask your parents if you can go to an NA or AA meeting. Even if you do not want to quit right now, you will still be able to get out of the house and meet new people that will accept you and you might get a good message at the same time.
