It's weird. Some days I feel overly energetic, can't stop talking to people, am overly irritable and keep trying to strike conversations with random people. Then there are days when I'm tired all the time. Can't find the energy to get out of bed and want to avoid any conversations with anyone. I drag my feet everywhere I go and can't stop thinking about getting back in bed, irrespective of how many hours of sleep I've had. It's more than just this, but I'm on a word limit. Should I see a doctor?
