I agree with earthshine, maybe that would help. Better get rest, somtimes a good breakfast in the mornings helps. I actually understood what you mean, almost everyday I would say the same thing, of saying "what wrong with me" to you the truth, I have a short term memory, so I struggle with school, because I easily forget things, what I've learnt and reamber what I have to do or something that's on. So I understand, try not to post the same things, for I think it is rules, it's better lf you try ask the mentor of this site. you know the funny thing, I keep having to go back and cheak rules once in while before I do anything else. XD
Anyway I hope the members advice may help you, or even mine. I'm sure it would get better soon, I promise.

everyone makes mistakes you know.
