Wondering again

This is what depression feels like..may be

The sky is blue with patches of white,
It seems that happiness has chosen the wrong side..
Day and night-I feel isolated
Wondering if i really am in the right?
Stale and thick-tired of myself
I am growing impatient,even the season has changed
Walked so slowly and yet missed it all
Wondering if it did happen or if i imagined the fall?
