The biggest breakup mistake you can make? Pretending that it didn&#39;t happen. You broke up for a good reason, and getting back together isn&#39;t an option. (Maybe it will be in a couple of years, when things have changed, but not now.) Until you accept this, you can&#39;t start healing.You&#39;re allowed to give yourself a couple of days to mope around and cry. Tear up some love notes, sob to your friends, and write some poems (just don&#39;t publish anything online - you&#39;ll regret it later). Letting yourself be sad will do you better than bottling it all up. After the second day of moping, though, it&#39;s time to start snapping out of it.You might want to call or text your ex, but resist the urge. You both need a little time apart from each other, or else you&#39;ll never stop hurting. In a couple of months, you might be ready to try out a friendship, but for now, try to avoid all contact.The worst way to get over an ex is to sit in your room all alone. Hang out with your friends and family, play some sports, hit the gym or dig into your favorite hobbies. It&#39;ll make you feel good and get your mind off of the breakup.After the initial loss, you won&#39;t be thinking about your ex nonstop like you used to, but you might find your thoughts trailing back to your breakup. Push those sad thoughts of your head and replace them with happy ones. There&#39;s no use dwelling on all the sad stuff forever.Breakups can be good excuses for fresh starts. Make a fun change: give yourself a makeover, get into a new hobby, join a new after-school activity or redecorate your room. It&#39;ll make you feel happy and give you a big burst of confidence.Time really does heal all wounds. The pain you&#39;re feeling now won&#39;t last forever, even if it feels like it will. So hang in there - it&#39;ll get easier. I promise.
