To chime in here -- I would be prepared for the worst case scenario... that they don't respond, that they are still not nice, or that they don't own up to their bullying behavior. I personally think that not much good can come from reaching out to friend them or from a confrontation and I would steer clear of it myself. You can find your own closure and within therapy. I do like the idea of writing notes to them without sending them. The thing is, bullies are typically not nice people and do not change. Some MAY grow out of it, but others do not. As you said, go into it with your eyes wide open and without expectation, but please be careful to not get hurt or retraumatized all over again. Sending my best wishes. ((((Hugs)))))
