It's hard to give advice on your situation without context, and I agree with the comments that a counselor would be able to help you more than we would.
But 20 years later, it's probably best to move on, not even think about them or try to contact them. Even if you wanted them to apologize rather than disregard you, either way, it doesn't offer any tangible value, and you shouldn't care about their approval toward you.
20 years later, you probably have a totally different job, location, social circle, hobbies, goals, etc. In school, you're forced to do things you don't want to do, but now you have a blank canvas, can do nearly anything you want; it doesn't make sense to focus your time/energy on that.
20 years is a long time to hold onto something. If someone told you that they were in love with this person that doesn't want to commit, and only wants friends-with-benefits, and they've been FWB's for 20 years, and the person still thinks there's a chance of getting married, you'd tell them they've been holding onto that bag way too long right? Similar concept applies here.
I had bullies. One died of suicide, and I felt bad for him and his family; I forgave him. But the rest, I don't have any resentment toward them either. They moved on with their lives; marriage/career/kids; maybe they're a kinder person nowadays, maybe they're not, but either way, knowing the answer won't really affect me.
