Coping with heartbreak for the second time

Ever since I was little I loved cooking. I met someone 2 weeks ago at my cooking class and we talked 24/7 we were up till 2am just talking. But then the other day he stopped showing up to class and stopped texting me, he never ever read my messages. We told eachother we were in love and I believe that he meant it. But I just don't know how to cope with this again. He made me laugh when I felt like there was nothing to smile about. I have BPD so I have my mood swings and my bad thoughts and all of this happening is just making everything so much worse. I try to distract myself but I find little things that remind me of him. I feel good like I'm getting over him but then an hour later he's back. I just don't know what to with myself anymore. I'm only 17.
