I`m nuts, says Justin Bieber

London: Teen sensation Justin Bieber suffers from insomnia and feels he thinks a lot. But he also believes that it could be a sign he is a good musician.

"I`m crazy, I`m nuts. Just the way my brain works. I`m not normal. I think differently - my mind is always racing. I`m just...nuts. But I think the best musicians probably are," Bieber has been quoted as saying by contactmusic.com. "I just turn over all night and think. My mind races. I think about all the things I didn`t have time to think about during the day - like family and god and things that should be more important but you don`t have time to think about, because you just get caught up in everything else during the day," he added. The 16-year-old enjoys fame, but says he realises his responsibility towards his fans. "It`s hard to really balance myself. A regular kid, if he catches the flu, he just gets to go home. But I can`t do that. Everything is important. But, you know, my sanity is important, too. Even if I`m angry, I`ll just put a smile on my face and fake it. I don`t often fake it - what`s me is me. I know I have to give up a lot of myself, or a lot of a private life." IANS
