It will pass. It feels awful, I know, but it will pass. I remember feeling like there was no way I could stay sober, but it was just thoughts.
Hang in there. Distract yourself. What's something you enjoy doing?
You'll feel positive again. It's normal to be on an emotional roller coaster at first. Ride out the emotions and they'll even out over time.
Fantastic that you're posting how you're feeling. Well done!
Best wishes to you!!
