Crazy!

why am i feeling to emotionally unstable?
i am angry, frustrated without any valid reason.
Just because i dont want to be the 1st to approach ppl and communicate doesnt mean that no one can approach me 1st. i m tired of being the 1st to everything.
I am tired of guessing and figuring out the mood that ppl having each and everyday. I thought i have done the max but given no respond.
Why cant anyone understand this?
I have been judged by ppl that i put too much concern towards it.
Is it worth? Or i am just being stupid?
