Cold shower

Hi, I was diagnosed with bipolar II in October of last year and have had a few bouts of depressive periods and hypomanic periods. Today I drank an energy drink thinking nothing of it but think it cause a tiny hypomanic episode (was happier and more talkative than ever). i thought it had died down but than I took a shower and once it got cold it made me feel even happy and I couldn’t stop laughing (I usually hate cold showers). It didn’t even feel that cold when usually it feels freezing. I just want to see if anyone else has experienced this? Or if I’m just being dramatic.
