That's probably one of the hardest things to go through with your parents. Remember, though, that so long as you visit them regularly wherever they end up living, they will be better off. That's really the most important thing though--make sure you talk to them once a week at least, and better yet visit them that often. It's hard for older folks to live without family around them, but in the long run, so long as they know you care and are nearby if they need you, you're doing the right thing in making sure they're safer.
