DAE anyone else feel like they don’t know who they are or have any personality?

Besides the voice in my head I never feel like I’m being myself like everything is a performance or copy of others around me. When It comes conversation they never last long because I run out of words quickly. Even talking about my interests feel performative and tiring. I think it stems from a childhood of bullying and isolation where I just wanted other kids to like me and be popular so I tried a myriad of personalities (none of them worked) and now I Just have no idea who I really am
