On day 7 of quitting a 300mg a day addiction to the limitless and pure7 tabs after a 6 month spiral

Last Friday at midnight i took my final dose of 7oh or anything opiate related. I've made it past the worst of the physical but the mental side is nearly as bad lol I spend nearly all day in constant anxiety and dread unable to enjoy anything to take my mind away as the clock continues move at a snails pace. This is my first attempt and I am prioritizing protecting the progress ive made but its so exhausting im also doing this without any other meds so its been one hell of a ride this week also worth mentioning my state just banned 7oh and now other stuff has taken its place like sr17 but I dont wanna pick up another substance after fighting so hard to get to day 7 anyone have any tips for getting through this anxiety?
