I think you are doing a good job - or getting better at - managing expectations. PN will hinder us - each and every person on this thread I think - but will not prevent us from living a full life. And indeed, many people are so much worse off.

Also: to be clear, improvement is still possible. I'm trying to be as honest as I can here, but things are always "in a context". I went from a level 7 to 8/10 pain situation to a usual 2 (with proper medication) to 4 (on a bad day). That is huge. But it's still chronic pain, and affects me, and I need to deal with that, and I have bad days with "why me?" too. But less and less so. Because I adapted my expectations to match reality.

Sure, no all day shopping for you, I get that. But shopping for a small hour is about a small hour more than I could manage after 8 months sober. It took me 2 years before I could go to a live pop-concert, standing for 1.5 hours, but sitting down occasionally for some relief. Still, I was up for about an hour though, at least. Felt like I finished a marathon and won the lottery at the same time.

So... enjoy that one hour or even 30 minutes you can manage. Festivities are a blessing to some, but a total drag on many many people. So yeah, try to have some fun nonetheless, and good on you for being able to think about those who are less fortunate still.
