Congratulations for making it this long, most other people wouldn't have. Day 10 is huge.
Painkillers not only numb you physically, they also numb you emotionally/mentally, so coming off of them can be a bit of a trip that way too. I suggest listening to some of your favorite music, watching funny movies, or things that will involve you *emotionally* in them in a good/positive way. You will probably feel things you haven't felt in years and that is always encouraging and begins to make you feel better and realize you can do this and it won't feel bad always.
