Why are people so stressed out when they have their period? Just have fun!?
Just Have fun ( that seems like a guy thing to say)
Periods affect people in different ways some people have cramps that are almost unbearable and need prescription drugs to bear it. Some people have hormone problems which are mood altering. I think most people want to have fun and dont want to dwell on their period but a period is a biological thing that you cant control . Have a little empathy for those people who have a more difficult period than you.
hormone levels surge and it can cause stress and anxiety...not so easy for some to just "relax"....
i do not know they just need to chill hypochondriacs
well our hormones can cause us to act differently whether we want to be in crappy moods or not! haha i suffer from pms half the time. & when cramps come & messy periods are around, you cant help but be stressed sometimes. ive gotten used to it & discovered the glorious tampon so i live easy. but for some its hard to relax & you just ogtta get through it!
its hormone levels they rise like crazy causing u to be moody
