Will organic chemistry haunt me for the rest of my life?

So last semester, I was doing good in organic chemistry. I got about high 80's on all my exams. I did pretty well on the final too. So my final average was an 87, but I got an A-. However, I know most of my friends who didn't do so well on the midterms, studied last minute for the final and aced it. The way my professor grades the cl is that he replaces your grade with your final exam grade. So technically a person who gets 0's on all their midterm with 100% on their final can get a better grade than a person who consistently gets 89's on all of their exams. I mean how dare he give me an A-! I am going to kill that guy! I am seriously pissed off beyond recognition. But no, it doesn't end there. I have to take orgo 2! I am too traumatized from orgo 1 to be taking orgo 2. Every time I am in that cl, I explode in a furious rage. Hate that cl so much that I just want to kill somebody! For now, I just have to put my frustration aside and get that stupid exam over with tomorrow. But seriously, when will this sh^t end??!! I keep seeing orgo everywhere. Someone please help! This cl is driving me crazy! Can't take this sh^t no more! Will organic chemistry haunt me for the rest of my life?
