Pessimistic Me?

sometimes i juz dunno wat i want?
i always makes myself being in a moody condition.
often feels hopeless, dreary and fear of failures...
i'm failing myself actually...

recently i found out my confidence hv dropped to minimum.
i dunno how to face everyone around me,
felt being neglected.
all tis feelings frustrated me.
leads me to aggression(verbally).

i cant stand any criticize any longer.
i'll break down.

hopefully i wont mad!
if i keep on thinking negatively i scare all the ppl around me will leave me very soon.
wat should i do?
to overcome negative thinking?

the problem is M I REALLY PESSIMISTIC?
OR I'M JUZ TELLING MYSELF THE TRUTH?

god!i'm confuse!!!!
