am I good enough? even failing at exchange exam?

look i don't wanna be negative right here but honestily i can't think i'm good enough on like everything and that pmo (piss me off)

so one thing i've always done it's learning and consuming english content and it really turns into my way out for a lot of things, just a way so i can express myself without my parents finding out or some shit like that, it's like escaping the shitty reality somehow and i genually thought i was good on it. So my school give me the chance to prove i was good enough on english to won a exchange and it was the moment of my life, i study really hard and got better in a few months but still i didn't pass. The second chance come in and i've got a lower score than the first time and i just keep thinking "what i do wrong?". Really i'm not a religious person but i've been praying since this first exam and still God won't let me have what i fight so hard to get. Am i really that bad at this? I'm not good at art, at english, at math, at writhing, at drawning, at swiming, wtf i'm doing w my life?? 

ik it's sounding like i'm crying over nothing, but that was my only chance to get out of this country for a few months and see new things and it just drips through my fingers like water after all the hard work and nigths without sleeping, everything just ended like that and i can't even cry about it bc "someone else deserves more than you" and those shit

(i write all of this by myself, only using translator to check if i write a few words right and yet i don't deserve that bullshit)
