Who am I?

Things used to be very clear. Who I was, what I wanted to do and where I was going. But now everything is up for grabs. Tonight I had to leave a bar to go and cry outside in the street. I realised I didn't know who I actually am. Do I want to live here, do I want to carry on with my job, do I want to carry on in this way? The answer to these questions is mostly no, but I just don't know how to break free.
