I wish I could say I'm shocked. But I'm really not. Some of these reactions were at the core of why I stopped writing several years ago (but there was so much more going on there!).
I think it takes bravery to share your truth, especially when dealing with past trauma and abuse. Especially since there are so many of us who are still struggling to share our own (or finding the boundaries we're comfortable with!).
Don't listen to the negative people. Yes, they should know better. They just don't care. Listen to those who are with you, who commiserate with you, who understand you. Those are your people.
