Ugh just let it end. I don't care anymore, Clinton's the nominee. I supported Sanders because I genuinely think he's a good guy and believes what he says, but it's over and Clinton won. I'm guessing the other Sanders supporters like me left and now support Clinton, so the more rabid ones remain in places like /r/sandersforpresident and aren't ready to give up yet. Accepting defeat is an important lesson in humility, and I hope for the sake of the country that these people come to terms with the situation of reality before November.
You have basically summed up how I have been feeling this entire primary.
