My situation is a little different yet similar emotions would exist now.

I grew yo in So. Calif. Los Angeles county. I actually lived for 54 years in that same area & hated it the whole time. Bad marriage I left after 33 years & moved 2100 miles away to a little farm I bought in a state where I knew ABSOLUTELY NO ONE. HOWEVER, I have met the most wonderful people & am involved in our little community & the area. I have so fallen in love with my new home & area & it is the happiest I have ever been in my life. I know that leaving here would make me seriously feel the way you are feeling & I finally understand for the first time in my life how important it is to be happy where we are living.

Shoot, if your mom is healthy maybe yiu could consider moving back & just visit.
