What emotions do we get on our period?

so i have been on my period for the past few days! and a while back i had this problem i would cry randomly and i wasn't on my period so i went to see the doctor and he gave me med. I took it every morning like i was suppose to but today i was wonder why i felt so alone. My parents go to work and its just me and my brother we do our hw that last 1 or 2 and then we watch tv to p the time. I was finished video chatting my cousin that lives in MI (i live in GA) i grew up in Michigan. i may be homesick from talking to my cousin is such a long time but i moves about 4-5 years ago! ow i felt is how people feel when someone they love dies. they feel alone like no one is feeling the same way and they lost the person they love and go into depression mode. that's how i feel but no one has died so i feel like loneliness has taken over. i don't want this happening to my brothers hes to young (hes 7) i don't think he needs this type of life i have (ITS NOT LIKE I WANT TO KILL MYSELF OR ANYTHING) I'm wondering if this is happening because of my period. PLZ list other emotions that happen during my period so if it happens i can decide if its not natural for it to happen on my period or not.
