Hi yes I can relate to the feeling of not knowing who I am. It's not just a feeling. I honestly have no idea who I am.
I kinda don't like being self aware. When I didn't know any better I really thought I liked all of the things I did with my friends but now I feel like I'm watching myself from the outside just doing what they do. Different things with different people. I can hold whole conversations on things I had no interest in before I met that person or before they were interested in it. But as soon as those conversations stop there is silence. I have nothing of my own to talk about.
I just feel empty. There is no other way to describe it.
