Giving up pills is hard. It was tough for me, but I got off of them. You are going to feel like crap while your body rids itself of the addiction. It wont be easy but there are ways to make it more tolerable. Drink pedialyte or childs rehydration drinks, stay away from gatorade as it has a lot of sugar in it. Eat- for now it doesnt really matter what you eat just as long as you get something in your system. Being dehydrated and hungry makes it ten times worse. Sleep. Get outside and get some sun light. Dont stay in doors as that tends to make depression and anxiety much worse. Do some light walking or hiking for a week. Then gradually make it a longer walk or hike then maybe start mixing in some jogging. Stay active will help you a lot.
