Does adhd, come and go? Sometimes I feel normal, then I get a spurk of hyperness energy, and can't focus, my mind is going 90 miles an hour...

Usually not. Adhd while its symptoms sometimes vary does not usual behave this way. What you are describing sounds possibly like a form of bipolar disorder. You should go over this with a psychiatrist as the treatment for the two conditions are very different and effective help is available for both.
