Within the first week, just let everything out. Cry, scream, write your feelings in a journal, anything that makes you feel better. Just let out all the negative things you had in your relationship that would make you want to kill yourself or whatever"desperate measures"you're talking about.After that, get rid of anything and everything that reminds you of him. This will help A LOT during a bad break-up.Next, spend time with the people that actually love you and care for you. Before you know it, you'll have moved on and taken him out of your life.
