My sister lives a mile from me and still doesn't visit (my place is 'below' her standards), but she has adopted a friend and tells everyone that she is her sister and will do anything for her. Which is funny because when I go into her community and people say "I thought Michelle was her sister" and I laugh and say, 'no, that's her pretend sister, I'm her only sister". This really p##es her off. Families are never perfect but can be very interesting.

After sharing that, I'd suggest you tell your sister what is really on your mind. That you really miss her and would love for her to come visit you. Tell her that truth that you are feeling left out. I bet she will try to come through for you. Family may be stupid at times, but they are not all bad.
