Does anyone else feel like you don't know who you are sometimes and your idea of who you are always changes. Mine greatly changes depending on the people I talk to and the type of environment I'm in. 

I'm struggling with this and have no idea if I'm actually as capable as I thought I was. I just feel empty sometimes. 
Other times, I feel very emotional and sad. sometimes, really motivated. and sometimes just nothing. 

I dont know how people perceive that. but its just so hard, and I've always felt so misunderstood because of it.
