There is no time like the present, my friend. Your beautiful little girl needs you to be completely present in her world. You CAN be free of these other things that are controlling you. I was just like you in that it was all or nothing for me as well. Now that I have 20 months sober and almost 16 months w/o weed just about EVERYTHING is so much clearer and easier to understand.
I am here for you if you'd like to chat in private.... so PM me anytime.
Have a GREAT clean and sober day tomorrow!
