So Sorry for what you're going through! Please Do not give up! Hugs. i agree with the other wise and wonderful posters about at least starting to distance yourself from her if she seems to bring you down constantly. You can still keep in touch with her for important Celebrations and other events but if you feel like she's having a negative impact on your Life then i feel like diminishing your contacts with her may be necessary unless she decides to change. i'd suggest to either do that or talk to your sister about how bad you're feeling around her i think. If she doesn't seem to change then i'm afraid there aren't a lot of other choices then. i Hope things will improve really soon for you and everyone. Love. Sending many Safe, warm hugs to BOTH you, @black-roses, your Family, your Friends and ALL of your Loved Ones! Keep fighting and keep rocking NO MATTER WHAT HAPPENS, OK?!
