what is wrong with me?!?

Lately like the last 2 weeks or so iv been super moody and irritable and overly sensitive... any little thing can make me cry and usually I have really tough skin... also the tiniest things are setting me off and I find myself starting fights with my man over literally nothing... my period isn't due for another two weeks so I have no idea why iv been like this... I hate it cuz I feel like I'm putting up walls with ppl but idk why but then when I feel them start to pull away I get super upset... ughhhh idk what's going on with my body and mind but it needs to chill out!!!
