So, I have this habit of  asking my doctor for drugs, and then abusing them right afterwards. I abused Prozac, Laxatives, and Risperdal. I've been doing this for two years (I think). I know I shouldn't be asking this on here but what type of problem is this? I was checking to see if the symptoms were related to Substance abuse, but one of my doctors say that medications aren't addictive drugs. So is it Substance abuse even if it's medications? (And btw, I wasn't diagnosed by my doctors with this disorder yet, and I'm not asking for a diagnosis because it's against the rules, this is a legitimate question I needed to ask).
