Stepping into Shoes that Aren't Yours

Argh..
WHYYYYYYYY.
So much restraint.
Too much control.
Hmm...
Have you ever tried to live another person's life?
Would you dare to step into their shoes?
Would you really take the risk of swapping with another person?
You could end up as a millionaire, or an actor or maybe even a god.
But then, you may also become a slave, a beggar or maybe just another regular Joe.
Would you?
I would.
That's what desperation is.
I just want to get out of this life.
I know I'm lucky. I know I have the essential things a human needs. But I feel so dissatisfied to the point I wish i were walking to a different school with a different name. Bullies would be fine with me.
Why do I feel this way?

Fine. I'll change the question to make it easier.

WHAT is making me feel this way?
