Dont worry about emotional withdrawals yet, because a lot of people who become dependent on pain meds have tapered off and not been mentally addicted to them. Worrying about them will just make any minor anxiety worse.The fact that you had it in your head that it wasnt an addiction can sometimes mean that you wont have much of a mental withdrawal because you werent taking it to mask some bad emotional problem (as far as i know at least).
Just focus on how to treat your physical withdrawal symptoms, and if its not completely necessary, i would avoid benzos at all costs as i have seen way too many people use them for withdrawals and then get addicted to them to replace the addiction they had with opiates, or to complement their opiate addiction. Just get through it and try your best to stay off of it. Because this is your first time going through withdrawals, you have a much better shot at not relapsing, so take advantage of that and steer clear of any regular use. If youre going to use it at all, drop it to once a week, twice max in my opinion. And try not to use it for sleep anymore as that will make it that much more difficult when you withdrawal because youll be dependent on them to sleep as well.
