Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
I would suggest do everything you can to not accept any more contact with the Ex than you have to. Move out, and if you get a phone call let the answering machine get it. If they send you a letter send it unopened to your attorney. Do whatever you have to do to protect yourself from any more overstimulation.
As to your sister, love her obviously but also understand you are limited as to how much you can deal with at once. As for your friend, how incredibly sad.
You can't afford to crash and burn, but on the positive side, people can handle so much more than they think they can. Some day this will be over. Breathe and accept support. So many nice ladies here care.
Hugs, Karen
