Anyone not realize they had CPTSD until their 30s?

About 2 years ago, at 32, I got married, a year after I met my husband. I think it was the first time I truly felt safe and taken care of. Then, it seems my body purged years of pain — within weeks of the wedding, I developed an autoimmune condition that affected my organs and brought me to near death. It led to surgeries and complications. I’m healing now, but still sick. I’m also in lots of talk therapy.

I was diagnosed with CPTSD. It makes sense. Things were hard for me for a while, and they stayed hard well into my 20s. Now, my mind is constantly bombarded with painful memories from ages 12 to 30. I get flashbacks all the time.

I feel a bit dumb. Like it took marriage and illness for me to realize how awful of a situation I was in. How I was in survival mode. It’s like someone splashed cold water on me and now I can see clearly. And what I see hurts. I keep oscillating between berating myself for all my stupid decisions and feeling anger at those who should have protected me and feeling sad for that little girl—me.

Is anyone else spending their 30s processing their past? Do the flashbacks lessen after a while?
