Often times when I'm feeling numb or empty I try to force myself to do something other than dwell on my own thoughts, like take a short walk, or call someone. I think numbness, for me anyway, is usually a response to feeling powerless in day-to-day things, like maybe a friend seemingly taking advantage of you because they know you won't say anything, or something similar. Again, this is just my experience, but maybe that makes sense to you? I just took my seroquel for the night and my brain has begun to significantly fog.
