Im so scared that im still lying

Okay so some months ago i realized ive been lying my whole life.

I have been in so much pain my whole life but i didnt know why and I'd lie about trauma, id exaggerate trauma, id lie about other stuff ever since i was a kid, just random stuff.

I still notice i lie randomly or exaggerate, it will be about more innocent things like when i watch a show and something funny happens ill explain it to people in an exaggerated way and ofc i always get so embarrassed when i realized people watched the same show and i explained what happened in such a wild way.

I have OCD and all this lying i did became like an OCD theme where now im terrified of lying and everything feels like a lie. (And i still lie about smaller things like i said).

Im so scared of becoming like my abuser, my mother, who would lie about everything and believe it, she would lie about anything in order to feel like she is a good person but she genuinely believes the lies and she is incapable of understanding she has done wrong.

Im so scared im her. Im so scared im lying about so much and don't even realize.

When i would lie about my trauma i didnt even realize, well i did, but the part of me that did, somehow got supressed, to the point i didnt realize, and it became this fantasy world. But then i realized that, when i get pity for fake trauma, i dont experience any of that pity or sympathy, all that pity they gave me was for FAKE trauma, not MINE. And that realization was so devastating for me that i never ever want to experiencing that ever again.

But now there is an issue, because i DO have trauma, and these lies, they were lies and stories based off of my fragmented memories (i was very young when i was abused so i cant remember properly what happened to me).

And another issue is that my fragmented memories seems to indicate i might have been severely abused. How am i ever, ever supposed to trust that...? What if im just lying again?? Lying for sympathy and pity?? Im fogged in this "bias" that i need certain traumas to be enough, so what if this bias is causing me to fake trauma subconscious?

But why do i get nightmares, flashbacks?

I even had the same fear of said person as a little child, as well nightmares of the same said person as a little child. How could i fake those fears and nightmares as a 3-5 year old?

There appears to be very real, genuine trauma, but as well, not real stuff, because of my bias of being "enough". This is all a disaster and im suffering so badly.

Please help me.
