It sounds like your mind is already pretty well made up about leaving, but I think for myself, the single most important thing I did in deciding what to do with my life was to read literature by XJWs and communicate with others who were going through the same thing. I think by hanging out and talking to the friends here, your path will gradually reveal itself to you.
I did what can only be termed a 'quick fade' where I just stopped going to meetings, moved out and never talked about my reasons for leaving with any one except my parents. I was lucky that I had someone to stay with till everything calmed down.
