How old are you and also have you become a thing lunatic right-winger? Two of those are common causes for friends drifting apart. 1) if you’re in your late 20s / early 30s most other people are busy with their own shit and don’t have time to engage with the people who used to occupy their entire existence. 2) if you became an unhinged rightwinger spouting insane nonsense then people probably don’t wanna engage with you.

Likely it’s just you’re old now so old social circles close up

Have you tried using your own memory?

Spend a decade commuting by bike if you can (rain or shine).

Get radicalized by the terrorists (people who just wanna have a nice safe society free of bigotry and hate).
