They will understand your hurt and they will try to make you feel better. Let them cheer you up. Distract yourself by throwing yourself into your schoolwork, taking up a new hobby or learning a new sport. Get active and you ll be too busy to dwell on what happened. This is really important.
Dwelling is bad.
Just try to make yourself snap out of it when you ve been feeling negative for more than a few minutes. Call an upbeat friend, play an impossibly happy song that makes you want to dance, remind yourself of how much there is to be grateful for in your life. Make yourself believe it.
