My friends, do not despair. No matter what sin you have done, Hashem loves you and wants to draw you close to Him. The Ramchal says in Derech Hashem that our slip ups  that make us feel far from Hashem but Hashem is non-the-less still there completely. Rebbe Nachman says, no matter what don't despair! He says even the mistake of masturbating one can repent of. So my friends, what is your heartbreak for? You made a mistake and now your just going to undue it and move on! I believe in you!
