Should I go to my high school reunion?

My reunion is coming up but I didnt grad. from there. I ended up finishing later. Should I still go? I’ve had people email me the info saying I don’t know if your going but here’s the info. I would also be going by myself because I’m single so that makes me more nervous too. I was never really close to any of these people but I don’t want them to be upset if I don’t go. I don’t know what to do. I probably shouldn’t care this much. I don’t know.
