PMS produces emotional effects such as mood swings. I tend to get angry and sad easier than normal. So I'm more irritable, more depressed and prone to crying, and I'm not sure about my anxiety. I do have anxiety, but not sure if mine gets worse then or not. Anyway, though, I think it is normal as long as it doesn't get a WHOLE, WHOLE LOT worse. If it is extreme enough, you might have an unusual case. It could be premenstrual dysphoric disorder (PMDD). But just because you have some degree of it doesn't mean you have PMDD. Some degree of this is just run of the mill PMS.
