I lied, I cheated and I stole from many people. I was a taker. That’s why my life ended up where it is now. Life is not a game. You can’t play around with life. It’s serious. I wasn’t honest with a lot of people. Even my mom and my brother and my family members. I isolated myself from my family members. I isolated myself from my friends. That’s not something you should do. If this happens, you probably have a mental illness.”Mental illness is serious. I hear voices in my head constantly and I don’t know where they come from. I just ask God for forgiveness for all the wrong I’ve done.”The UCLA basketball team released a statement on Twitter on Tuesday.
