Am I really sick? or i just feeling it?

These days, when i meet a 'special' situation.. i feel kind of sicky.. 

feel like vomiting, but ntg to vomit out.. 

feel like dizzy, but actually i'm not.. 

feel like crying, but i cant cry it out.. 

it's like my heart being squeezed tight by an invisible hand

i hate myself for being like this.. 

someone, anyone...

maybe it's just smtg to do with stress?

or its just...
