Could i have schizophrenia if i am sometimes energized and happy and other times sloooow and blue?

No: Schizophrenia is not about energy level or mood, it is about impairments in reality testing that lead to hearing or seeing things not there and have impaired reality testing in other ways. What you describe could be just normal variation; if it occurs frequently and seemingly independent of what's going on in your life, you might have cyclothymia, which has mood swings of the sort you describe.

Most likely not.: While anyone, including someone with schizophrenia could have fluctuations in their mood, if you are having times of high energy with decreased need for sleep, very happy mood and feel high on life and then other times are depressed, lack energy and maybe want to sleep a lot, this could be a mood disorder assuming it is not substance use related. Your primary doctor would be a good place to start.
