So here is a common experience we can pretty much all relate to, I'm going to keep it quite general:
You were in a relationship, you developed feelings for that person, now the relationship is over and you feel hurt.
Simple, huh? And let's not underestimate how much it can hurt. Just think back to the last time it happened to you and the pain you experienced. I am not talking about the time it happened and you didn't feel pain. I am only talking about the time it happened and you felt just horrible inside.
Now, what did you do (or what do you realize now that you could have done), to heal yourself and be happy again?
PS. My goal here is to come up with as many tips as possible, not so much a bunch of people repeating the same tip over and over. The reason is because no one tip will work for everyone, so the more we can come up with the more likely this thread could help people.
