Never be sorry for sharing what you feel. You are right, keeping it inside kills us.
That voice in your head is your disease, do not let it win!!! Stay clean and keep doing the next right thing. I know it sounds cliche but it is ture.
What about step work, are you currently working the steps with a sponsor? from my own experience I can tell you that it helps.
And keep sharing, we are all here just doing the same thing, trying to stay clean and live life on lifes terms, just one day at a time.
