Feeling like poo

Good morning sorry bout the rant but I am soooo upset not only do I start my period, like a period from hell! Been ttc since April ? I'm 27 why is it so hard everytime I have a period it's like I wanna just cry and lock myself away! Why is it so hard :( also Been issues with my other halfs sister. We have been together almost 2 years but she's obsessed with his ex! His ex had a baby with her new ugly man and the sis wanna send him pics and try start up convos between them two :8 honest today I feel like goin mad at everyone
