Lisa, just an outsiders observation, but it sounds like more than ever this is the place to be. There are so many kind, supportive people and leaving when you're in a sad, lonely place could make you feel more detached and alone. Unless you have a solid support system outside of here.

You appear to have good perspective on the fact that the person who left that nasty comment was wrong and that's good. You have a lot of good wishes here on this post. Try to take them in.

Whether you decide to stay or go, I wish you well.
