Who am I

I'm lost.....
who am i....
I don't know.....
They win...
I'm exhausted.....
Should I stop thinking and get over it....
I can't....
This thing is still messing my head....
I'm a coward....
I have an extremely low self-esteem....
I just find it hard to define myself.....
Majoring in Psychology?....
I guess I couldn't do it....
Am I optimistic?.....
I'm not sure....
Just tired.....
I'm a really coward who is useless....
They win...always win....
I'm just a loser......
