Is it normal to be this hyper and forgetful
So um i'm typing this quite late at night so ima keep it simple.. basically everyone i know thinks i'm a maniac because i'm extremely hyper and i have very big and wide eyes so i sometimes come off as creepy or something. like in the middle of class I will just kinda die laughing for no apparent reason other than the fact that i am just happy. Some people think I am high or something but i swear I have never been high or drunk I am just a very hyper person. I'm also quite disorganized. I lose everything, including my memory and attention span. This happens once or twice a day:
someone does something
me: what are you doing??
person 1: uh you just said that i could [enter verb here]
me: (after thinking very long and hard about it) i don't remember that.
person 1: you JUST said it. hey [person 2] didn't sagittarius just now say that i could [enter verb here]
person 2: yes.
me: oh. okay then haha
so does this happen to everyone or am i just paranoid
