A brief comment on your celibacy journey: Like you, I decided to be celibate (its only been a month for me). However, I didn't place a time when it will end. A friend of mine said just live and do what comes naturally. I am creating new platonic friendships with men and women. With the men, I am blunt when I tell them "this is strictly platonic; I'm not ready to date anyone; I will make a great friend but awful girlfriend." If they really just want to be friends, they will stick around. If not, they showed their true colors and well, good for me. You don't have to shut yourself off from the world (or men) because you are celibate or focusing on your health (Unless that's best for you). Make new friendships.
Back to Pluto:
"Pluto deals with the destruction of that which no longer serves us so that we can move forward in our evolutionary journey, and we would expect a conjunction with the center of our galaxy to be a course correction on a planetary level. It is unlikely that this will come as an immediate wave of advanced consciousness or significant events as many people are prophesying; it is more likely to be a shift deep in the core of our awareness that brings about a more groundbreaking change of direction on the planetary level."

Use this time to heal. I believe what is going on allows us a chance to look inward. Why do you need a break from relationships? Whay are you becoming a cynic? Why do you feel lonely.
