What have I done?

I've done so many things to my friends, I can't forget all the mistakes I've done towards them. I feel so guilty, just because my mouth. KERANA MULUT, BADAN BINASA. Heck, that's a true fact fyi. I don't know what to do anymore. And I'm trying to change myself. I don't even understand myself. I don't even know who I am. My life has been unstable just like my finance. Goshh, all I need now is a time to rest and a sleep wouldn't be enough. I need someone to calm me, and tell me that I'm wrong when I am. I need to think before I speak and I need to think before I acted. I'm going to hold on to that motto, hmm. Not in a good mood, chow
