idk what to di😢😢💔

Me and my boyfriend are in a long distance relationship and we've been dating for about 3 years now. He left yesterday and idk when I'll see him again I can't stop crying..I feel like I can't breathe I hate school bc I see couples literally everywhere I look and it takes eveything in me not to break down crying😢😢💔I miss him so fucking much it physically hurts
