Sometimes...I feel useless...and used...

Salam all...

I'm a bit down few days ni...dunno why, but I feel useless...and like being used...I dont want to mentioned names...it's something that I rather keep it to myself...=( I cant help but thinking...am I that bad? Am I so stupid? And..am i worthless? I've tried my very best to do everything, but it seems tak guna...nobody appreaciate it...it's like, I'm not exist...org treat macam kita tak ada perasaan, tak ada keinginan and tak ada impian...and, org treat kita macam org bodoh...=(...
