Unable to remember most of childhood

I am unsure.

I think I might have trauma I repressed/don't remember that caused me to not remember most of my childhood.

But how do I find out if I do?

How do I know if it isn't just that I dissociated most of my childhood and it's just a dissociation problem?

Since I do currently have problems with dissociating daily. But haven't been diagnosed with a dissociation disorder.

I tried telling my pdoc that I am having problems with dissociation but he keeps changing the subject or just brushes it off.

Before anyone says to change pdoc, it isn't that simple for me.

My pdoc is part of the reason I was able to get social security/disability money.

If I change pdocs that might get taken away. Which wouldn't be good.

I could try seeing a therapist again but I am unsure.

I still live with my parents at the age of 22 (almost 23).

I do have my own room but if I were to go on Zoom with the therapist. I'm afraid my dad would hear what I am saying. Since his room is nearby and he has to be in there for work. Since he has been working from home.

There are no other rooms that I could go to for privacy.

I can't ask him to go downstairs and work because his setup is in his room. He has a desktop computer and he's a IT guy.
