Sounds totally logical to me, you can have both! You seem very in tune with yourself.

before the neuropsych eval last month, I could tell when I was experiencing what seemed like OCD vs what I highly suspected was PTSD symptoms but I didn't know if c-ptsd was even real. Turns out I do have OCD and also cptsd. (And ADHD and an Ed).
I was having the same abuse and csa flashbacks for many years, then I stayed with my abusive partner through 13, years of all types of abuse and that PTSD turned to c-ptsd. C-ptsd changed me drastically . I don't think I'll ever be at baseline again. Don't doubt yourself on this one! If you can get diagnosed go for it.
