Don't worry about it. You won't be the first nor the last person who changes their mind on a job change, and I promise they have had it happen before. To retract your acceptance you should just need to terse but professional. The general format would be: - A sentence indicating you're withdrawing your acceptance of the offer. - One or two sentences explaining you have an unforeseen unique opportunity.
