Missing piece

Life is a puzzle
Not in the way that it's confusing but everyone expects you to fit
They expect you to be their perfect missing piece and if you aren't you get left out and left behind
Constantly changing yourself to fit is tiring. Constantly changing yourself for others is tiring.
I'm tired of trying to fit.
I'm tired of changing my sides in order to fit perfectly. In order to complete their puzzle
The sides don't add up and I can't seem to solve the puzzle.
What if I belong to a different puzzle. Going from puzzle to puzzle to find where I fit and I can't find it. I don't fit.
As much as I try
I do not fit.
