Missy, forgive me, but you are an adult now. You need to live your own life. For a parent to expect their child to put their life on hold just to cater to them, well that's just wrong. A parent who truly cares for you would only want you to be happy and find your place in this world. That they would instead choose to put you on a guilt trip says more about them, and their dysfunction, than your obligations toward them.
My wife was in a situation very similar to yours. Her parents were older, her father was an elder and they were hard core JWs. They put every sort of guilt trip possible on her and kept her at home until she was 27. Now that Nina has distance (and 21 years of marriage) she looks back on the decision to stay there as one of the biggest mistakes she made.
Remember God doesn't make crap. Your gut is telling you what you need to do. Live your life and be happy in your choices.
