I am 4 months sober as well (well, I will be Tuesday, at any rate!) and just finishing up the 8th step (still need to go over it with my sponsor).
Tell me a little about your program-- how have you been working the steps? What is your sponsor like? How often do you get to meetings? How is your relationship with your HP? I think all these things can play into how you are feeling at this stage in your recovery.
