When I was in my 20s, I worked in retail. I was suffering from undiagnosed complex PTSD, I was being abused at home, and I didn't like my job.

There were times when I was mean or rude to customers. Looking back at it now, I am ashamed and embarrassed by the way I treated people.

I am sort of haunted by the memories. I keep replaying it in my mind. I feel bad because that is not who I really am. I'm not a mean person or a jerk.

How can I forgive myself and move on?

I tried to logically approach this and tell myself that I reacted the way a person with undiagnosed complex PTSD would react. It doesn't work. I'm still embarrassed and ashamed.
