I am coincidentally also 35, and had similar sentiments following my most “recent” divorce (4 years ago!)
Your comment is bang on mate. The second to last paragraph really hits home but it’s something that I really needed to acknowledge and accept if I ever wanted to move on.

You just gotta find your vibe, and it takes effort, but once you do others will see your vibe and want to jiggle with you (I’m not great at analogies hopefully this makes sense).
In ear earbuds. I blimmin’ hate them but my Audio Technica over ears are too bulky for the gym.
Bit off topic, though if anyone could recommend cheap but decent wireless headphones, for the gym, that are not in ear I would appreciate it a lot (I’m in the UK).
