I just can't see people in pain any more

I've had a rough year medically and for much of it I was in so much pain I couldn't move without pain releif. It was just hard.
I'm trying to move on from it but every time I see people in pain, even if it's just on TV or in a video game it all just comes flooding back to me and I panic and I need to sleep it off. I'm not resiliant any more. I can barely watch shows for adults any more without skipping around. It's just so hard. The other day I was playing a video game and I was fine while I was fighting monsters but the second I fought a human enemy and I heard the pain grunts and everything I just shut down and I was too low to even go to sleep that night. I had to take sleeping pills.
I am working with my therapist but I don't know, it's hard as I do have my breathing techniques and I do try to do distraction stuff, I play connections every day, I try to have music on, stuff like that. It's just with my other trauma history and with my DID and sutff it's like any time I get seriously freaked out I become little. and it's so embarassing having a little girl version of you be mentally stronger than the supposed grown up.
I just want to be able to not get freaked out by pain I guess
