I too have many times where my emotions are blunted. I simply do not react to anything anyone says or situations I find myself in. This causes me great distress and bothers those close to me. There are times where I can react appropriately but I cannot force myself to when blunted. I am so sorry you experience this too. I don't know what to do about it. I don't think it is solely because of my meds or illness. I think it is part of my personality too. I find myself reacting on the inside but cannot seem to draw it to the outside some times. I am working on it. Sometimes I fake it a bit and that helps draw a true reaction up. This doesn't always work but it is a start.
