Good job! You know, learning that the world isn't going to fall apart if we don't do our "job" by worrying about stuff is a HUGE realization. It's sort of like what I went through when I first had to deal with uncomfortable emotions and upsetting situations without picking up a drink. It's like "OMG, I CAN'T!!" But each time you DO it, and realize you aren't going to die from feeling uncomfortable, and that the situation does resolve itself without "help" (whether from worrying or drinking), the next time becomes easier.
Good job!!
