Not sure how i feel about going to high school reunion...

Back in 1987, I was diagnosed with leukemia in February of my senior year and missed the last 5 months of school. My treatments and bone marrow transplant that followed were anything but easy and for a while I was living hour to hour. Now, it is 25 years later and I have a family, home, job and things are good...and the high school reunion is being planned for September of this year. I'd like to go to see everyone but when I think of going, I find that it brings back memories of the difficult times when I was sick instead of any good times I had during high school so I'm leaning toward not going. Just wondering if anyone has avoided situations even though not directly related to illness...
