Don’t give up! If you’re serious about it. The first few weeks are when your brain is really speaking out to go back. I’m about to hit 3 months sober and the first few weeks were the roughest and I’ve been fine since. I’m feeling better every day, but it’s a process, and I think it’s important to do kind of a “systems check” notice and appreciate when you’re feeling positive or having a good time not drinking when everyone else is.
I can’t imagine how you’re getting through this everyday, invisible disabilities really do suck. I hope you manage to get it diagnosed properly and start a treatment plan to manage the pain/heal from it. It sounds like an autoimmune condition.
