I think there will be plenty of time later for all that.
Sober time makes things much easier, I don't think you need to do anything at all about this right now unless they bring it up. People know that others make poor decisions when under the influence. Do you think you could do it no matter what their reactions might be?
Be kind to yourself right now. In AA, where "amends" are used - apologies aren't done in the first month necessarily, and it's done with the help and guidance of someone who has been sober and who has gone through their own amends.
Early sobriety was a very emotionally vulnerable time for me and I didn't offer up any verbal amends until I was back to feeling strong and supported.
Have you gone to meetings or talked to a spiritual counselor about this?
