Good on you for throwing the vodka away.
I agree with finding your own place. Have you looked into finding a place? Even if you are out of work now there are social housing schemes available and out of work benefits to help you find a place.
I do wonder if deep down you aren't really wanting to leave home? Somehow you and your parents are in this vicious cycle-you are dependent on them, they treat you like a child, you accept it and it continues. It is comfortable, financially etc by not having to live alone but for your own sanity,sobriety and development it's necessary for us to break from our parent.Who knows- it will probably do your relationship with them the world of good
Nothing will change if nothing changes
