I have one older sister who recently turned 21 who I am very close with. For the majority of the time she is very easy to get along with because she has a very sunny disposition, is very energetic, kind, and is has pretty solid communication (for the most part). However, she is an entirely different person when she is on her period because she suffers from Premenstrual Dysphoric Disorder, PMDD, which Mayo Clinic describes as, “…a severe, sometimes disabling extension of premenstrual syndrome.” The situation happened as I was returning home from a friend’s house: I was walking to my room upstairs (which is across from my sister’s) and assumed that my sister was upstairs because I could hear Netflix coming from her …show more content…

Her behavior was very aggressive and intense, as illustrated when she snapped at me for inquiring if she had emptied the cat box. Her other behaviors included groaning, loudly complaining about things, briefly calming down to pet her cat, then ramping up again when he phone started to fail to work properly. So while it may seem strange at first that my normally easy-going, kind, affable sister was behaving so erratically, once I was informed about, and consequently considered, the other factors affecting her behavior, it suddenly seemed much more appropriate for her current psychology and physiological
