I did this with Xanax and Seroquel about ten years ago. I ended up in IP. In my head it wasn't a suicide attempt, I just wanted to relax and not deal with life. But from the outside looking in, it was a suicide attempt. So I would think it is some form of self harm because you are in a way literally harming yourself with taking so many pills unnecessarily. As hard as it may be, I would let your pdoc know.
