Why do i get this sense of emptiness within me every now and then?

Maybe because i'm starting to feel the stress.
Maybe because i'm still unsure about the next steps to take in life.
Maybe because i look at some of others' current lives and accomplishments and cant help but be filled with envy.
Maybe because i wish i had more.
Maybe because i wish i could.
Maybe because the grass always seem greener on the other side.

Maybe because.. i wish there is something more out there for me.

And i'm reaching out. With uncertainty. Hoping for just one thing. But sometimes, as though my fingers grasping at mist, all i feel is nothing.

Emptiness.
