Is this a hormone problem?

For the past similar to 3 weeks I haven't gotten any sleep. I cannot fall asleep at darkness or take nap during the day anymore. I own a really hard time getting up every morning. Also I never get the impression like doing anything anymore. My friends and boyfriend adjectives ask me to hang out everyday but I take home up excuses so i can lay in my bed for hours and chomp through and watch tv and article. My period also comes every 3 weeks and i hear that is not everyday. My mom says this could be a hormone problem and that i obligation blood work done. Can someone tell me if this is only my body changing or if i do requirement blood work done? You could be depressed. See a gyn.
