Regularly, after meditation or reading spiritual books, I get "epiphanies" (new pieces of information about myself, my behavior and/or the outside world), which induce strong emotions in me. I lose productivity, sometimes stop to meditate for a couple of days and need quite a lot of time to recover. Sometimes, but not always, I get an understanding of what should I do different now (based on that epiphany).

As a result, I learn too slowly.

Since I'm probably not the first to experience these problems (depressive state after learning things about me, which require me to do something differently), there is probably advice in Buddhist writings about how to fix it (so that the learning part remains and the depressive part is reduced or eliminated, i. e. the time between an "epiphany" and new way of doing things is minimal).

What does Buddhist literature (especially from the Diamond way Buddhism) recommend in this situation?
