Hi and welcome
You could try experimenting with turning the soundtrack way down if you're distracted by the sounds. It's what I've done right from the beginning and it really helps. The restlessness and discomforts are just old stuff + resistance, just as you said.
I believe in the old saying, "The only way is through" We just mask our feelings and issues by distracting ourselves most of the time but once faced, it's remarkable how they fade away ...now or later.... Better out and dealt with than in and causing dysfunction and disease!
Here's to success on our cushions!
