Just want to give you a heartfelt and a HUGE congratz on graduating AND opening your practice!! I dont have much advice tho, my gut says that the whole cards on the table apology will work in your favour, as those close to you, are still close to you, even tho you've mistreated them in the past... Maybe an email would be a less intimidating approach for you to take? I think that you'll be better able to forgive yourself once you have 'proof' that your loved ones have forgiven you.
