sometimes i don't like change

About 50minutes ago, I successfully transferred the cell phone's responsibility from my uncle to me, i should have been happy, because I wanna change it for a long time. however, the fact is that I didn't felt good, I'm not happy, i actually felt unsteady. it's not like just change the user's name, the account number has change, the billing has changed...i hate this, i hate the sense of unstable. at that time, i was kind of upset, sort of regret. I'm thinking, why i felt bad on this? I'm not sure if it related to money, maybe...because money stuff is always makes me nerve racking...
