I studied electronics and worked on some complex systems. CRT TV systems were pretty complicated. Red, Blue, and Green cathode ray tubes and tri-phosphor tubes. LCD TVs are not near as complex as the CRTs they replaced.
I digress. How something breaks can give insight into how that something works. I lost my positive emotions following a powerful temporal lobe seizure. My parents and siblings seemed alien to me. I believe the reason for that was because
I was no longer able to decode the emotional context of my memories of them. A memory can be a fairly complex thing with color and texture and lots of detail. If you damage the section of your brain that is necessary to
analyze the details, then you are just left with an image that seems alien without the emotional context. So, if you are working without emotions, I think it is fair to say that time is on your side. Well, either you are getting
worse, better, or staying the same. As long as you are not getting worse, you are getting better. My emotions returned slowly. I kept doing the things I knew I enjoyed, until I started to believe I was enjoying them again.
In time, I was enjoying them again. And, my parents and siblings became familiar again also. Good luck.
