I can definitely relate in many ways. Sometimes I feel like being me isn't unique and many other people are like me. I feel like everything I do has already been done by others. Even saying (typing) these exact words. Though many people tend to say I stand out and that I'm a great person with a unique personality I find it all to be rubbish. This is why a turn to my stories and writings. To be what I want or what I wanted through my imagination and experience. So every time I'm feeling like I'm just another person in a crowd, I turn to stories, imagination, and books. I search for the thing I love and that gives me comfort. Sorry if this was long or if you don't want to read this but I needed to tell somebody this, and it's because it's true. Also, I would love to hit you up for a writing partner- fellow Potterhead!
I get this; i've heard quite a few people talk about it, and sometimes I feel this way except I try so hard to mirror the other person that I sometimes mess up.
you're definitely not alone in it!
