It all started when i suddenly experienced theese episodes of feeling extremely high energy and happy. In school I would experience these episodes quite often and I would change from being really happy and high energy to feeling mildly depressed, tired and hopeless  in only a few hours. My friends often got really confused by this and joked about everything being bipolar which lead me to researching it and relating to it alot. I have bad sleeping problems and i get irritated by smaller things and I experience racing thoughts which all seemed to be symptoms of bipolar disorder. But im not sure about what the difference between bipolar disorder and cyclothymia is and if I have any of them.
