I think it can be summed up by a conversation with a friend in my last few days in Israel. He said, "Your departure will be a loss for the country." In Hebrew. Which means I had become fluent (enough), built meaningful relationships, made a positive impact on my community, and had created memories that will last me a lifetime.
I got to mentor a high school delegation of teens going to America to educate their peers on day-to-day Israel. I translated a coexistence magazine from Hebrew to English. I visited the West Bank. I camped on the Kinneret at Pesach, where I was one of the only Americans around. I saw every facet of Israeli society and fell in love with it all, accepting the faults with beauty of the country.
