OK sounds like you know what you did wrong.
You have a sponsor, you worked the steps, and you've made progress. (You didn't mention meetings here?) Then you "rest on your laurels and forget to put first things first".
Part of the issue, as I see it, is that you need to deal with acceptance. You have a disease. You need to take daily treatment. "God grant me the Serenity to accept the things I can not change". Like a diabetic, we have a simple choice, accept our treatment ... or die. Very simple. The great thing is that once this is accepted, things get a whole lot easier.
I urge you read this:
Key to Serenity - Acceptance Is the Key to Serenity
It might help.
Give over what you can't change and change what you can. Simple
