Call or email my sister at least once every two weeks

"Do Unto Others" item number five was to call or email my sister at least once every two weeks. After quite a lot of trying and hearing nothing in return, I've given up. If she wants to contact me, she's free to do so. Anyway, I have my own issues to worry about and I can't deal with the stress of hers, as well. She was on the right track but now she's gone back to handling everything poorly. She's going to drive me crazy if I don't distance myself a little bit.
