Hi Jezzi. I wanted to echo what others above said. IT WILL PASS!! I had some days in early sobriety where I just didn't even want to get out of bed. 'Doom' is a perfect word for it. SR helped a lot, and I had/have some people close to me that I can be candid with about my addiction struggles. The fact that you posted instead of drinking says a lot, and you should feel pride in that. Get through today. Even if you can't get yourself to do anything but lay in bed and read/post on SR, stay sober today. 11 days is awesome, by the way. You've definitely got both feet in the door at this point, so stick with it. The emotional roller coaster is really common for a little while after the physical stuff ends.
Keep posting! We are all here for you.
