Help me please

Okay so firstly, sorry for my bad english! I don't know where to start!

I am not trying to self diagnose here!

I have been diagnosed with Ocd, dpdr, ARFID and anxiety disorder by my Psychiatrist and psychologist!

Currently my meds are going on for Anxiety and Dissociation! And next visit he would be adding meds for ocd!

But my patterns are worse! Something is deeply wrong with me and i can feel it! The patterns match more of Cptsd! I also had a ptsd episode last year for a month! I don't know how to put it in front of my psychologist!

I have a strong reason for thinking it's Cptsd

I was SA ed by my cousin when i was 11 and when i finally refused after a week of it! He started calling me names and in general bullying me!

I don't know if the nightmares are about that! Because i genuinely don't think about that moment! I am really confused! My reaction time is delayed by years too!

Can someone tell me how to tell my psychologist everything! Since technically i haven't shared anything traumatic with her till now
