I’m so bored

My boyfriend and I have been dating for 7 almost 8months. (It feels like a lifetime and I love it) but he just went away today to his sisters house in Florida. He’s only gone for 3 days but it seriously feels like forever. All I’ve been doing is sitting in my room bored as hell. Also I’m getting period soon making me super emotional and crying all the time because I miss him ( Ik sounds stupid Bc he’s only gone for a small amount of time) but what should I do ugh help! (Also idk which topic to put this under so that y I put relationship)
