Sorry to hear that, I have some serious health issues that while not impacting me much physically often leave me drained after work (and the meds while amazing don't help) and escaping into VR feels so much more relaxing than playing the same game in front of a screen (in part because I spend all day in front of a screen for work I think), it's hard to describe to someone who hasn't done it but after an hour in a good VR title (my favourite example been Project Cars 2) your brain accepts the VR as something close to reality.

I was playing the other day driving around le man in a thunderstorm and when I took the headset off and it was beautiful sunshine outside I was sorta surprised.

I've found using a good set of headphones really helps, the Rift S is a cracking bit of kit but the built in speakers are weak as hell (but they put a 3.5mm on the side so who cares, headphones are great).
