Nothing will change if you don't make changes. Why do you think you are suddenly going to have a great relationship with your man friend who treats you so badly? It will carry on as long as you let it.
your new friend isn't going to keep you sober, as your car won't.
Only YOU can make the changes you need. I had to be at the stage where I wanted to be sober more than I wanted to drink and be determined to do anything to do it.
