No, I understand what you are talking to. We have to make our way somehow, even if it means being unhappy now for what we hope is joy later. My mom and dad are so proud of my Ph.D endeavors that I would find it hard to quit based on that alone! They'd be so disappointed, even though they would probably never admit it. They dream of having a huge party for me when I graduate. I'll just be happy to have them both at my side on that day. I'm very lucky to still have them. So even though I'm suffering now, I keep my graduation day in my mind and tell myself this is worth it even on days when it doesn't seem to be!
