yeah i can't speak to your branch's recruitment needs b/c every local is slightly different, but it's very possible they were just prioritizing certain areas/demographics. but def hit someone back up! whenever a good volunteer-comrade fades away, our first thought after "a certain amount of volunteer churn is inevitable" is "damn, what are we not doing well enough when it comes to retention???" so there's a very good chance comrades near you are bummed that you fell off their radar and want you to come back!
also some of our most dedicated cadres were active friends of the party for years before becoming members, so try not to be discouraged! i do feel you though re: paranoia you did something wrong, serious political organizing can kinda be extreme exposure therapy if you're already rejection sensitive.
or going absolutely insane like they saw 
or similar.
Wot if a Tales from the Crypt eppy were two and a half hours long??
(angry that i'm sleep deprived at work because i stayed up watching The Substance - fun-if-shallow mids if it were a tight 90 but at that length i'm leaning toward active dislike)
