I'm diagnosed but very much questioning...

I an diagnosed with PTSD not CPTSD btw. So I don't actually think I have PTSD while I am well versed in some mental health diagnoses which I also have (autism, adhd,bpd) but I have been researching those for years. ptsd? Ehhh not exactly an expert lol. But from what I have seen ppl with ptsd get physical flashbacks I have never once experienced that. I have been tryna pay attention to myself and wen I get upset but most of the times I get upset is wen i get overwhelmed by noise. And i choose not 2 think abt my childhood anymore ive done that enough wen I was younger. It feels like theres something im not remembering...but how would Ik i cant fucking remember. Shit maybe i dont wana remember. I just dont understand this diagnosis rn...im thinking maybe its possible for ptsd to effect me in other ways but not flashbacks? This is something im very confused about. I had thought my problems came from my bpd i wasnt even thinking abt ptsd previously.

So ig my question is who else thinks they are wrong? Or am I just confused
