what cannot be

I'm stuck. 

I'm in the middle of my own crossroads. 

How confusing this life can possibly be?

   There are things that I want to do but I shouldn't,

   and things that I should do but I wouldn't.

    Time goes and so does the things that I forget but I must remember,

    but why should the things I remember are those I need to forget?

I've yet to search for the answers. I've yet to come up with clues. 

Still, I wonder. Why must we keep on pining on what cannot be?
