Believe in your worth. You may undervalue yourself in the moment of a breakup, but your value doesn’t depend on someone’s ability to fully appreciate you. If you wrap your identity around the relationship, the pain you feel is that you’ve had to sacrifice that part of your identity. If you expected one person to fulfill all of your needs, then of course there is a vacuum when they’re gone. Now that you’re single, use this time to build a community of people with shared interests whom you want to be in your life forever. Make yourself whole. You need to be someone who makes you happy.
