Emotional

adjective (of persons) excessively affected by emotion

Being emotional doesn't mean that you have more emotions, it means that you are more affected by them.

High estrogen levels are associated with greater mood swings, and greater reactivity towards emotions. The infamous Roid Rage is actually caused by elevated estrogen levels as a result of the elevated testosterone levels from steroids. If steroid users don't use estrogen suppressors, then the body attempts to balance the hormonal levels and produces excess estrogen, which causes dramatic mood swings. Women are naturally susceptible to this because of their fluctuating hormonal levels during reproductive cycles.
