Sorry you are having a bad day mittens - but just remember that it's completely normal to have bad days, just a regular part of life. Being sober definitely gives us the ability to feel a lot better, and to do just about everything better - but it doesn't prevent us from having a bad day here and there.
Check your "HALT" ( hungry, angry, lonely, tired ) status and address it if you need it. Sometimes the weather or a bug or whatever just throws us for a loop too. Taking a walk, reading a good book, watching some inspirational video, etc - all things that can help.
Coming here to check in and talk it through is a great idea too, glad you did. The one thing that we know for sure about bad days is they do end...and good days almost always follow!
