Oh Cory, my heart goes out to you. It is the worst grief imaginable, there is nothing to make it go away but they say time will heal everything. It is okay to mourn the death of your MR, like the others have pointed out it does not mean the end of the world. I know it seems like it and you are desperately seeking answers, but slow down. Tonight and tomorrow will be the worst nights probably, after which it will slowly but surely get better. Can you take a vacation or a break for sometime? Change of scene might help you and do things you have never done before. Open up avenues in life you havent explored before. Stay with friends or family today and tomorrow, make sure you are not all by yourself. I can imagine you may need space to grieve alone but having someone just in the next room even helps beat the loneliness. You are in my prayers tonight, I hope god gives you the strength to go through this. We are all rooting for you, there are better days ahead.
