The concept of medicating a patient is, as I see it, not to "medicate away" feelings or experiences, but to allow the person to have and feel more normal emotional responses to events - whatever those events may be. I look at meds as a "screen" that filters out extremely painful and overly intense emotions, feelings, reactions and allows a stable perspective on life events. So in that way, medication allows me to feel and to better cope with life.
I've discussed this subject at length with my therapist. She has told me that clients who need medication, but are not on it, tend not to grow in therapy. But clients who are taking the medication that keeps them stable are better able to do the therapy work and benefit from it.
