Briggsys girl,
For god sake DONT stress out. If you have to move away for the rest of your pG .I would do it. My mum died of cancer in 05 and because of the way my siblings treated me before she died( mum died 7 weeks after my miscarrage) I lost our baby girl at 19 weeks, stress was the likely cause. I still cannot forgive them and they are no longer a part of my life. Truthfully I have never felt better. You dont need to have ppl like that in your life even if they are so called "family".
Take care of yourself and Im glad you have reconciled with the "good" ones. Very true, Ppls true colours do eventually show through.
