I am glad you came here.
Living with your parents must be tough but you can take control back of your own life. His drinking unfortunately is not something you can control. You can put one foot in front of the other and get a job for yourself, protect your funds and one day at a time work your way out. With him or without him.
If there are ANY Alanon meetings in your area I would suggest that. There are some powerposts at the top of this and the Naranon forums that are a good read. There are books at the library..Melody Beattie..Alanon literature. Hnang around here and share with us. There are people at all stages of recovery here.
Welcome and make yourself at home!
Hugs,
JT
