Have you tried family therapy? Maybe that might help you to get through this. Your family needs to know when to stop. When my mom was doing stuff like this to me I had just told her to make up her mind and then I moved out. I didn't see her for about 3 months after I had moved out. Then she had decided to change because she knew it wasn't right for her to keep going back and forth like she did all the time. She got scared when I was gone for so long and I didn't talk to her on the phone either. So she changed and now she thinks before acting. Any way take good care of you! Hope your day gets better!
