I have some memories, and , like Allheart said, initially I had only fragments but more has fallen into place.
I didn't go into therapy to work on that issue, so for me we didn't work on it...we worked on other stuff but as the relationship deepened and I guess I trusted my T, more stuff came up. If it comes up, we look at it, if it doesn't we work on other stuff, whatever I bring.
I agree that there's no point forcing memories. I wasn't looking for mine at all, cos I didn't know they were there to be found.

For me personally,the memory gaps feel disempowering and painful. I don't want to remember necessarily but I'd like to be able to choose if I bring something to mind or not. Also, I can see now that issues I have had (phobias etc) have probably been the I remembered, unprocessed stuff showing itself in other ways so, for me, I feel I will be healthier, stronger and saner in the future if I can process at least some of it.
