I get the same thing at times. When I'm out with friends, it never bothers me and I always know exactly who I am and what I'm doing, but when I'm alone I keep wondering what kind of person I should be.
Eventually I decided. It was a rough draft, but I saw what kind of person I wanted to be. I did little things to push myself into becoming that. I worked out a little more, I honed my speaking skills, I became more outgoing and social. You might not know exactly what you want to be right now, and that's only to be expected, but if you have some rough idea then you should start working towards it. It's never too early or late to start becoming the person you want to be.
Someone once asked me why I call myself Unimportant. Simple, I said. As a nihilist, that's what I see everyone and everything as. In the end, we are all Unimportant.
