Today my therapist told me I may have CPTSD

After 2 years of going to several therapists but not ever getting the help I needed, I started therapy with a trauma therapist a few months ago. Now after months of me talking in therapy, she told me I may have CPTSD and to read and look into it.

-emotional neglect of parents, emotional abuse from parents

-unreliable home environment with my parents always fighting and dad abusing mom

-dad leaving us for some years in our childhood

-not remembering a lot of my childhood, just random memories that I need to focus hard on

-possible physical abuse from mom (that I can’t remember, but I remember her locking my sister in a dark room and slapping her and me etc)

-possible sexual abuse from a male babysitter (still can’t remember, I was very young, but I have some weird memories)

-a few years ago I opened up about my possible CSA to a therapist who didn’t handle it properly. I had panic attacks, vision blacked out, was terrified after that session

-after that I slowly developed panic attacks whenever I went in a car or somewhere new, felt like I would publicly wet myself, couldn’t control my thoughts that something bad was going to happen to me

-during my childhood I turned into a very withdrawn child who had no friends and couldn’t speak or smile. I was almost mute and very socially awkward. Its like I was just in a haze for so many years

-dissociating problems in childhood where I used to build up a fantasy world and read a lot of books and play virtual world games where I was another characters

-maladaptive daydreaming in adulthood where I escape to my fantasy world while listening to music

-a lot of issues with relationships and friendships. Felt like killing myself if a guy I was really attached to, didn’t pay me attention anymore. Codependency issues, abandonment issues

-very low self esteem, used to have body image issues, had no sense of self and huge people pleaser

-suicide ideation

-Ive been sexting with guys who didn’t give a shit about me and sending them my nudes just for validation that I matter to them. But they used me and I felt horrible but still kept doing it like it’s an addiction

-absolutely no relationship with my dad currently, going into extreme alert mode when he’s around. Scared to speak to him

Can this all be signs of CPTSD? I just don’t want a wrong diagnosis and end up with a shitty therapist again. How do I know for sure that I have this thing?
