Being middle aged, and no friends

Don't worry, you're not the only one.

My advice for you is: Start doing something creative.
1 - Buy a metal detector and start an Youtube channel with your findigs.
2 - Do art, poetry, something creative.
3 - Fitness if you can (set a goal).
4 - Travel, if you can afford.
5 - Do repairs, if you know how.
