Have you considered talking with your doctor about getting sober? Getting thru the first week of not drinking can be rough, but sometimes meds can help the initial detox symptoms.
A face to face support group, such as AA, Lifering, Women for Sobriety, Rational Recovery, can be very helpful also, as can counseling. I see an addiction counselor once a week and it helps a lot.
As to your parents disappointment if you don't drink... sorry, mom and dad, but you're doing this for your own good - for YOUR own good.
Stick around here, read and post, and welcome to the family!:ghug3
