Hi pretty much the title been tired/ sleepy the majority of my day for the past 7 years or so.

Spoke to a doctor about it and he said it was depression and suggested I take Prozac but I don’t think I have depression? I’m not like depressive or want to kill myself just that I feel tired and want to sleep a lot more than normal.

He also did a blood test and everything came back fine except that I had just a tad high cholesterol level.

Don’t think it is diet either. I have been maintaining a steady balanced diet for the past year and I feel the same as when I used over/under eat.

Have a mostly active lifestyle. Job keeps me moving and I work out at home. Tried taking a bunch of vitamins but stopped after it had no effect.

What else could it be?

Edit: forgot to mention that I have no prior issues and am not taking medicine for anything
