PTSD not valid

So I have PTSD (obviously being in the group) and Anxiety, I have a SDIT to help me with it. The PTSD is from multiple sexual assault/rape events. Although sometime I dont feel like my PTSD is valid. Its not like I was kidnapped or really brutally abused or raped, its not like I was in the military. I knew every one of the guys that hurt me, I didn't fight I froze. I didn't say anything to anybody, I just let them walk and live their life like nothing happened. Ik all that doesn't mean my pain isn't valid or that my PTSD isn't valid. It's just sometimes my head tells me it's not, sometimes it feels like I should be complaining or shouldn't have PTSD bad enough for a SD because other people have been through worse. I dont have anyone to talk to about any of it (no therapist or whatever because of covid) i literally have no friends and don't hang out with anyone. And its hard, the only thing I do is come on here and post anonymously because of the fear that someone ik would see my post. (Ik stupid).

Does anyone else feel their PTSD isn't valid.
