My relationship with my cheating fiance is over, I've never been so depressed and I need help?

You are going through something truly terrible. It's always hard to end something you thought would last forever. The way you can cope with it is by knowing that the worst will soon be over. This emptiness and confusion you feel won't stay with you forever. It's extremely difficult to look ahead because of the pain, but there will be a day that you will be able to look back on this and realize it made you a better person. The worse thing that could have happened is if you married him and had children with him. Imagine this pain you are feeling being multiplied tenfold because of children involved. Be grateful that you spared yourself more pain and don't have to deal with a hard divorce. A break up is hard and I'm not minimizing it at all, but I just want you to see the bright side. You know he's a jerk and you are better off without him. He will be someone else's headache. Also, this man disregarded your feelings and your health with what he's done. If you haven't already, please see a doctor right away. 1 out of 4 people will contract and STD in their life. And with his track record, you don't want to find out years from now when you try to have a kid but you can't because it turns out you're sterile now. Don't mean to sound harsh, but I'm being honest and trying to help. Your health is most important here. The future holds good things for you. You will find the real love of your life, not the illusion. This is an exciting time to look ahead. Your options are now open. I know it's still fresh, but once you begin to accept it all, you *will* feel happier than you do right now. Don't be afraid to reach out to someone you trust. Being alone isn't always the best thing for you. Good luck
