I recommend being very honest with yourself here, whether or not you want to share it in a reply.
Is the low chance of bad consequences the only factor keeping you from talking to strangers? There’s a low chance of bad consequences when you cross a busy street, too.
Is fear of rejection by an individual or group a factor, too? There’s a much higher chance of that happening, but it’s far from life ruining.
Are you worried that you have social behaviors that make it more likely you are considered creepy in social interactions? If so, are there ways you can reduce those behaviors?
Are there other areas where acute awareness of severe potential negative consequences makes you avoid activities that lots of other people in your cohort might enjoy?
