Getting so overwhelmed/frustrated that you yell at inanimate objects? Been there done that. It's normal.

I used to take way too many pills myself. I have gotten to the point where I don't need to take a lot anymore. Just don't take anymore and don't beat yourself up over it. You might want to start cutting back on the number of pain relievers you take initially. Just take one or two instead of six. It will suck at first because your pain won't go away at first. But eventually your tolerance will lower and you won't have to take high amounts for relief. Just a suggestion. It's how I cut down. Taking too many pills is not good for your liver.
