Hi Lisa, that's got to be hurtful. Did they talk to you about what you had done, or just skip right to pushing you out?
Have you thought about asking why/how long you're being shut out?
I don't understand it. The only times I have shut people out is when they have overstepped repeatedly, or ignored me so we keep having the same argument. I can't really understand what has gone on here. Are your sisters being over-protective of your mother, or is your mother creating the friction?
I don't understand what you could have done (that's not abusive) that would cause this kind of dynamic. It sounds like they aren't treating you with much compassion. Do you have very different personalities?
