I would say take your time on this one. Getting sober is one thing, worrying about relationships is a whole different level of things you may not want to even consider at this point. Making amends is a formal part of 12 step programs, but it can be part of any sobriety plan if you choose. Again, you need to give things time - you are literally less than 72 hours out from getting so drunk that you posted that you wanted to strangle this same person you are meeting tomorrow. I understand you didn't mean that literally, but put everything in perspective - you need to work on your own sobriety first and foremost. And that takes time.
