Only Darkness Right Now

I just need to vent out today...
I am not feeling good at all...
Rather am miserable to the core...
Totally pissed off...
I just started liking my life..
People around me didnt seem to be so bad today...
After ages I felt calm and peaceful today..
Just relaxed and happy with myself..
But again everything changed within a minute..
The peace, the tranquility, the calm just vanished..
Fears, Memories, Past Emotions just seem to crowd my mind..
I know I cant change things that have happened..
Its just out of my hands...
But am unable to come to terms with things...
The old peaceful me has vanished all of a sudden and left behind a DARK DARK shadow of gloom and despair...
