oh ya, my newest story that i could tell u guys is kinda a sad one.....last time, i already told Nazrin that i dun like him anymore, but actually, i still do, i told him that b'cuz i dun wan him to take me as an admirer anymore, i want to be more like a fren to him, the one that always could be there for him and etc.....but yesterday i was so hurt by him because he actually scolded me b'cuz of something that i was just joking 'bout...i just kcau la her best fren ney, nama dy Fadhilah, evryone was teasing her that she likes Izzat(one of Nazrin frens and mine too), so i was joining them la, then out of all the people that teases her, i was the only one that got scolded by Nazrin, mane la xsdeyh, i was the ONLY one! haih.....when dy marah tu, saya trus repli 'k' je, then trus off9, da la that time i was so emo, kna marah ngan my dad sbb apa ntah....then, dy xmntk maaf or anythng......after a few hours, i go on9 back, i posted somethng that is so emo, pastu baru la dy nk terhegeh2 nk tnya kenapa saya mcm tu.....my post is 'bout u la! OBVIOUSLY! haih.....after that, i trus off9 and tido, and now here i am, all refreshed......the one that is very understanding and the only one that knows 'bout this is MUHAMMAD NASRULLAH....he's my tution fren and my new best fren, i know him early in the year but we're already close now, he understands me a a lot....thx Nasrullah~! :) another one that kinda want to help me but he's too late, but it's oke, i still appreciate it, i'd like to say thx to AIMAN ABDULLAH, dy nk pujuk saya and try tnya wats going on tp saya xnk bgtaw dy sbb dy one of Nazrin's best fren, but he's a nice guy, so is Nazrin, but he's the one that makes me depress the whole night......anyways, thx for reading guys, appreciate it a lot...and i'm already feeling a bit better now, except the one that's confusing, my FEELINGS, that is not ok yet.....anyway, i'll update soon, thx for reading, bubye~! :)
