Hi, welcome to PC!
Well, as for making amends I guess you might need to think on a person by person basis instead of thinking as a group. Taking people aside on their own to personally apologize for personal wrongs might be easier. Plus you can then gauge who will be more receptive and who won't, because each person is different. Using your sobriety as part of your appology would be good because you can say, "I've been sober this long and making amends is important to me."
Now, as the for the bipolar part, I will be honest and the unfortunate truth. Bipolar is not really accepted by a vast majority of people as an illness. It's considered a fake thing that is overblown by the media and people seeking attention or wanting to relinquish responsability for their actions. Very few people understand it, including people in healthcare, and even fewer people actually care if you tell them you have bipolar. It's the stigma we all live with that people with bipolar are crazy, heartless, and dangerous. We rampage the countryside and destroy everything... according to these people.
So, disclosing should be done very cautiously. Again, person by person basis. And sometimes best not to tell at your job (and you have your own practice so that's good.) My philosophy is a "need to know." If they don't absolutely need to know, then I'm not going to tell. You'd be shocked how quickly people will change on you if you disclose...
So your apology should just be from your heart. But the bipolar, that's a tricky one.
