Addiction is psychological. There is no such thing as "physical addiction" -- and if you mean physical dependence, that only means that if you stop taking the drug you'll go through withdrawal. It really has nothing to do with addiction. There are blood pressure medications that cause physical dependence but that doesn't mean people are "addicted" to their propanolol. You are deep in denial. Especially if you've convinced yourself that four years of learning about Freud and Piaget somehow makes you qualified to interpret and prescribe psychiatric medications. They don't even allow people with doctorates in psychology to do that! And rightfully so, because it's a completely different field of study! Wake up and quit enabling your mom.
