I've learned that most people get over things pretty quickly. I'd say just keep going as you are, but remain conscious to not repeat bad behaviour. If you ever run into someone that was a victim of your behaviour, it is a great thing to apologize with the sincerity you obviously have. You really can't do much more than that. Hiding from them, in my experience, causes far more stress and anxiety than a short confrontation and an apology ever will.
