I'm so sorry, I don't know the situation but heartbreaks hurt. From my experience with my ex was that listening to sad music doesn't help at all. You have to get yourself out of the depressive state in order to fix your heart again.
There are music compliations of happy music and pop music. You can also get uplifting songs that make you feel cool, or make you laugh. Some of my favorites would be DojaCat and kendric lamar.
I promise it'll get better, and you'll find someone just for you very soon. Just hang in there
