Nobody can really know the situation. Yes, some people are overmedicate, but other people truely do require a variety of medicines to lead a normal life. And ultimately, your girlfriend has to make the decisions that she feels are best for her health. And yes, there are risks with taking any medication, even Tylenol (er maybe especially with Tylenol!), but as long as she is being monitored by a physician, there is every reason to think she will be just fine. Other than perhaps encouraging her to get a 2nd opinion, I'd drop the subject. Don't marry someone thinking they will change, so you will have to decide for yourself if her being on meds is a deal breaker. But think of it like this, would you be considering this if she were on Lantus, metformin & captopril? Do you not believe that psychotropic medications are treating a physical problem in the brain, or do you think psychotropic medications just work as placebos? What if you married someone in perfect health, who later developed problems? Personally, I think its your partner who should be worried about progressing the relationship further with you, if you are considering dumping her now because of health problems (which apparently are being controlled with medication.)
