I am sorry to read of this difficult time. A divorce can be overwhelming and devastating to young children but this is equally so for adult children of divorcing parents.
My best advice is to act as normal as possible if your parents have to be together, particularly during special family gatherings. Leave them enough room to sort themselves. They will appreciate your reason for giving them enough space while they are in the same place. And do not tiptoe around them, either. Remain casual and observant and be ready to diffuse tension.
As your parents are divorcing, you may experience a lots of feelings. Your emotions may change frequently, too. You may feel angry, frustrated, upset, or sad. You may feel abandoned, afraid, worried, or guilty.
These feelings are normal and talking about them with a friend, family member, counselor or right here in the forum is a good thing.
I admire you for working with your counselor on CBT and remember this is a life changing event for you so give yourself permission to feel and know we are here for you.
We know where you have been and what you going through so stick with us.
I wish you peace,
Kitt
