Advice for a 27 year old

I hate everything about my life. I don't have a car anymore, I'm living at my Dad's for the next however many years, I can't get out of dead end jobs because that's all there is in this town, I hate my body 5"7, 65kg). I haven't progressed at all in my life and I don't know how to get out of this rut. I live in an old person's town. Never had a relationship, although this is the least of my concerns right now.
