Does anyone else feel like they’re two different people at the same time ?

My OCD just feels like a different person .. I wasn’t always like this. I only vaguely remember a time where I felt whole , and that was before high school. I haven’t felt like myself in years. I’ll write in my journal as if I’m talking to me as a different person. I use “you” instead of I and “We” instead of I as well. I rarely ever refer to myself in first person unless I’m writing about an experience or a memory I have. Does anyone else feel this way? I feel like I’m not in control of myself 95% of the time.. I always say to myself “I wish I was normal” “I just want to be happy”. On top of that, I don’t feel like I’m turning 22 in 2 days. I feel like I’m turning 12.
