Figuring out life one step at a time

Sometimes I wonder

Sometimes I wonder of the choices I made,
Sometimes I wonder how life would have been if I made some other ones,
But How can I explain this feeling other than distraught.
This is the state I only can get slow and sad.
So I end up covering my face with a smile and go fast,
I had asked myself numerous times, of what I did la-di-da.\
