How does one deal

With heartbreak... I mean I’ve never felt actual pain when it came to a person. Me and this guy are graduating and going down diff paths. He’s moving to a new city and I hope to move to his old city. We haven’t even left and I balled my eyes out in the shower from the pain of saying goodbye and we haven’t even said bye yet!! 🤦🏼‍♀️🙆🏼‍♀️ and the other day my body was in legit pain. Idk what todo all I keep doing is crying. Some reassuring words and advice are welcome.. I just don’t wanna be upset anymore I mean there’s only so much makeup that will cover swollen eyes
