Sometimes you just have to throw out whatever you have left and hunker down Rupert.
If you feel unwell, even if it's at work tomorrow see a Dr.
I think you need a better plan than the one you've been rolling on.
If you want to get your act together, work for it, especially a few days from now when you feel ok again and you think you maybe overreacted.
Think about more support - and more changes to your life - changes that better reflect your desire to get sober and stay that way.
Things may be bad - but they're not irreversible. The sooner you act the sooner you never have to feel this way again
If you're not sold on AA Google other meeting based approaches like SMART Recovery or LifeRing?
