Well, first I never listen to sad/depressing music cause that just worsens the situation, I would listen to like happy songs or something to keep me positive and hopefully happy or not sad. another thing I would do is try to move on.. and OF COURSE to keep me happy and to make me laugh I watch, PewDiePie and other funny youtubers like KYR SP33DY, smosh, furious pete, epic meal time, nigahiga, bad lip reading and Many MORE.... Hope this answers your question
