I love my family, but hate my hometown... not sure how to deal with it?

I don't understand why you stayed so long. I'm thinking it's the guilt of hurting your parents, but you can not live your life for them. Are they physically unable to care for themselves? If not, go. You've wasted half of your adult life living somewhere you do not want to. Today's technology allows you to keep in touch in so many ways. If they wanted you to, you could talk to your parents everyday from another country. In addition to needing excitement in your life, it sounds like you need self punishment also. There's no one stopping you except yourself. If you want out, stop complaining and just do it.
