For the past 2-4 days, maybe longer. I have felt very disengaged from my emotions; as well as people. I find myself faking emotions, facial movements and body gestures. Basically, I feel like a sociopath trying to act human. Or a space alien trying to fit in with humans. Every emotion and gesture is calculated. I feel as if I am here but mentally not. This will go on for weeks at a time. The longest was a month. Each time I start to feel somewhat human again this happens. I have been stressed out lately though. Just ranting, I suppose.
