I think my period has ruined me :')

It`s me
I came on last night which was expected, i've had terrible cramps and felt like shit most of the day and tonight i've literally only seen my boyfriend for 2ish hours and idk what happened when my mum mentioned him going home i just burst into tears because I didn't want him to go and ever since i've literally felt like i could cry and cry, i'm trying to get on with important college work but all i want to do is lie in bed and sob
