My mother experienced severe denial at first, she's from the MI doesn't exist / Pray it away generation...
I gave her some of my most horrid posts to read through tho, and that set her straight.
Generally my family is quite accepting and supportive, everyone always knew I was a nutter, a pdoc was just kind enough to give it a name.
TBH, I didn't feel very supported at first, but that's cause what I was wanting (someone to talk to, a shoulder to cry on) wasn't what I was getting. What I was getting was less chores, ramped up free child care, and solitude or distraction, PRN.
When I recognized their support for what it was, I became much more appreciative and no longer mourned for the type I didn't have... I managed to get that somewhere else anyway.
