Not to be short, but to frank, finish school and then leave. How much more University do you have? If you have been working there for three years, I would imagine that you have another year and you are graduated. Power through it, get the diploma, and leave the area. Sometimes in life we have to endure bad times to get to the good times. You have endured so far, and it is hard, but keep going and then find something better for yourself.
