Many people have it and Now my mom and she is normal but my and my dad, my brother, a grandfather and a few cousins have it but my mom is thinking maybe I might have it she says I am acting that way whatever it means she says I am at that age but I feel fine so what should I do? I don't feel different I feel energetic and electric and I feel really good I am just fine really I have been going throuhg positive changes I think she doesn't know what she is talking about but how would I know? I know how they act I am not acting that way! I thought since you people have it you could tell me what to watch out for or to know if I am starting to develop it. Thanks.
