Coming into this one a little late I think but I just wanted to let you know I understand that warm fuzzy feeling at the thought of spending time with family.
My family is rather emotionally dysfunctional. I wasn't abused by a family member or anything, but there is years and years of everyone tip-toeing around one another within my family that is just adding up to a gigantic load of crap.
I have my good days and my bad days with them. Things have been somewhat easier since disclosing about the abuse.
Hope your dinner went [or will go] okay. I know how hard it is to put our old masks on after we've been at the healing thing for a while. Maybe every once in a while though is good practice
All the best,
