It passes. It sucks for now, and might for awhile, but it is what it is -- a feeling, a rut. It's not permanent, it is only a mental state, and it will change. The hard thing about sober time is you have to give it time for things to improve. Sometimes that means days, sometimes months, sometimes years.
The one thing you can do is not drink or use for one more day. You do that by chalking up a sober minute, followed by hours, until you go to sleep.
It's simple.
And then you wake up and reflect back on the incredibly powerful, strong, nearly impossible thing you did yesterday, which was not drink or use.
And it starts again.
