my club hosts sessions for beginners to group riding. the beginner groups get an experienced leader, no dropping and a formal introduction to etiquette and expected group dynamics.
OP needs something similar. don't worry about choosing a slow ride, it's better to learn how to handle yourself in a paceline and around others without being near your fitness limitations.
