What are the steps to forget bad memories?

Bad memories are about to ruin my life,how do I tackle em?

You have to move on! Try not to re-live them. The more you do, the more you'll remember them and the more vivid they will become. When you start to think of Em, tell yourslef to stop and think about something that will make you happy. You will probably never forget what happened. And that's okay, because our experiences make us who we are. But you can stop yourself from thinking about it often or by making it a nightmare you have to deal with every day of your life. Also, keep yourslef bisy. This will stop your mind from wandering into bad places. Did you know even faking a smile, actually can make you happier?
