I was wondering how much you are using your Steam Deck? And did the games you play on it change since you bought it?
I find that I used it a lot when I first got it, but my usage has gone down in the mean time. That’s mostly because I play games that are not a great fit for the Steam Deck (strategy, building, etc.) and I prefer to play those on my PC.
Some bpap sessions helped me get off bed after COVID, and gym helped me get back to “normal” after some months. Don’t know if it can help you, but hope you get better.
