Thanks, everyone. I've always been compared to other people, so it is hard not to continue that myself. I think at my next t session I will get him to go over what he/we know so far, as in reasons, splits, effects, etc. Obviously neither of us know everything, or even close (I just started seeing him in April), but it's been a bit since we did up a summary.
I'm also thinking that perhaps it was just more than she was aware of, as we'd only really ever talked about the little ones before.
Amandalouise, thanks for the input, and for sharing your personal story with me.
