Believe me, “I know how you feel” is a great response. Many people don’t, and never will. I think that good days and bad days come when they want, and that you just have to roll with it. One minute you’re crying, the next you’re laughing — it’s all real and part of life. That’s the only way I can properly describe it, or try to understand it, but I think it works.
