I've had those very same feelings myself, many many times, and like suzie I get caught up in comparing myself to others (more than I'd like to admit). All people are different in some ways, similar in others, PTSD or not. My T has had to tell me at least a 1,000 times that it's not healthy to compare myself to *anybody* - only to compare myself to where I once was. The view from here changes, even just a little, every single time I am reminded of that.
Hope it helps you too, even just a little bit.
I get the same shit going on with loud noises, ambulance, etc... sometimes even a memory out of nowhere will send me for a spin, or I can't go outside today because I'm hyper self-conscious. It's gotten better though, and I'm having good days again... looong overdue. I hope spring is a-poppin' in your neck of the woods... get out with the kids, play in the mud. What the hell, right?
