don't let these feelings overwhelm you ... (easier said, than done). that's still your AV screaming trying to get you to feel weak, unbalanced, scared... getting you to think about drinking. that's how AV is dying.
past is gone. you cannot live in the past, you have to "live the solution". move forward, go though this hell of the next few days... and you will come out stronger.
life's situations are not going to disappear. you are much better off dealing with them sober. what seems like a mountain of problems will look like a little bump in the road in a few weeks. you are getting better and stronger every hour you win this battle.
for now take care of yourself.
eat well.
try to get as much sleep as your body needs.
got for a lot of walks.
exercise if you can.
meditate.
pick up a new hobby.
keep your mind occupied with something simple.
