Drinking always made me get down on myself even more harshly than I would sober for years.
That's an old tape that should be replaced with positive self-talk.
The drink really does get us both mentally and physically, but you are on the sober road now--the bloat and puffy red face will go away, the sparkle will come back to your dull eyes as your system clears.
Most importantly, the dark mood will lift and you'll begin to see in a more positive way. By practicing that now, even if you don't yet "believe" it, you'll accelerate the process and make it happen much faster.
You can do it--you are worth it
