The first thing I had to learn was that feeling overwhelmed was not a suitable excuse to drink.
Drinking made the overwhelmed feeling worse
Make a list of things to do each day. Make it a reasonable list - one load of washing, 30 mins cleaning up..what ever you have on at work that day.
Try to accept that you're not going to feel great or think straight for a while. You're recovering from a bender.
Do your best at work cos thats all anyone can ask of you.
Relationships - depends on the relationship. If you're married I'ddiscuss thigs with your wife.
If you're single I'd stay that way for a while - wirk in gettign to knwo whosober you is for a little while.
If you're still living at home - up to you whether you want to bring up the subject of recovery or not.
expect to not feel great for a week or two. That's the price of a bender - but it's a finite time - you will feel better again - and you never have to feel this way again
