Don't know but I cry sometimes…

Some times I get fed up of this world (hell!!!)
There is no specific reason but it happens...It may be the environment which lets me get irritated. I am not a weak person mentally or physically but there is something which lets me. Ahhhhhhh...can't describe, it lets me cry...!!!!

Don't know but I cry sometimes. May be I miss someone, but I don't miss any one….
May be I hate someone, but I don't hate anyone too…
Nobody lets me cry but I used to.
May be it’s a feeling which I can not describe...why it happens...I don’t know. I become too depressed...
