I can sympathize. When you don't feel good about the direction your life has taken, then talking or visiting with people from the past only reminds you of the disappointment - at least that is how it affects me. A friend from high school called me several months ago. I called him back, but I deliberately cut the conversation very short, because I felt that he had progressed and succeeded in life while I had not. I feel bad, because he probably wondered why I wasn't as friendly as I should have been.
I hope you do better than me in your meeting. Good luck
