normal?

Why do I feel like I've drank a million energy drinks, when I haven't drank any! My body is shaking because I have so much energy & I constantly need to be doing something, I haven't slept for days, but I don't even feel the slightest bit tired, and haven't eaten cus I don't feel hungry and I'm rushing around trying to find something to do that I forget to eat! Like it's 11pm, I'm wide awake and in the middle of doing my assignments, and I have so many imma be up so long doing them! Euggghhh is this even normal? Like 2 weeks ago I had 0 energy, was crying ALL the time & tried to commit, now it's the opposite 😩🙄
