What to do when the heartache just won't go away?

maybe because of your last relationship...im the same way,i had a relationship with this really close friends of mine annnd one day he never came back..(online relationship my bad) buut i knew him for a very long tiem so i knew he wasnt like a perv or anything...buuuuuuut i think you should just take a break from anything,get a funny movie,snacks and just relax ^_^
