I need to let go of a toxic part of my life...my dad and his new family (which includes my step mother and 2 half sisters). I haven't talked to my dad and stepmother for over 4 years and I feel the only way to help myself heal is to let go of my sisters as well. It's been an ugly situation for a long time and I haven't been able to fully move on. the constant updtaes and family pictures or vacations don't help. I don't talk to my sisters at all, we are just friends on facebook, but I want to let that go. One is in college and the other is still in high school. How can I tell them I need to let go for awhile? or is this not the best decision? I need help!
