How to avoid apathy in the absence of self?

I have noticed in my meditation / mindfulness practice the following: as the idea of self dissolves, the ideas of compassion, happiness, sorrow, and basically everything that a "person" might experience also dissolve. This is disconcerting for a few reasons: 1. I stop caring about the suffering of others. After all, "no one" is really suffering, so there is no "person" to receive compassion. The "person" that I direct compassion to right now, is simply a volatile "soup of phenomenon" that won't even exist a few moments later. 2. I lose motivation to do things because I don't feel fear the way I used to. Because of my upbringing, fear of consequences was the primary motivation for doing anything. Example: in relationships, fear of letting people down would motivate me to pursue resolution to problems, resolve conflicts, etc. 3. I don't enjoy things in life the way I used to. As negative emotions have dissipated, so have positive ones. I no longer enjoy eating a meal with good friends, or a sunset or a dozen other things I used to. No moment is particularly better or worse than any other moment. When I live life one moment at a time, there is nothing to "look forward to" because I am not doing anything I dislike that I am trying to "get done as quickly as possible." Bottom line: the more I meditate and live moment by moment, the more dull and uninteresting the world becomes. Consequently, I don't know how to get from here to having compassion or even interest towards other living beings. Can anyone offer some guidance?
