Have you ever badly needed to move on from something? Most likely. A place, a person, a memory. I get where you're coming from. It can be really hard to know when to move on and what to do next, but that doesn't mean it's not the right choice. If something is not bringing you joy and happiness anymore, then walk away. You don't deserve to be this sad over something you have no control over - focus on bettering the other aspects of your life and letting things go.
