By "accepted" did you mean "approved"? In the context of immigration petitions, "accepted" usually only means that USCIS received it and cashed the check, so be careful to use the right word to avoid confusing readers.
When was the petitioned filed? Given that there is at least a 10-year wait from the filing date until the case is ripe for a consular interview, you will age out of eligibility and there is nothing you can do about it, unless the petition was filed more than about 5 or 6 years ago.
