As someone in their 20s without social media, I have exactly 0 friends. I live in a central European country and everyone around me has a friend group that originated during their childhood; they have childhood friends. I do not, mainly because throughout my time in school I switched schools a whole lot for various reasons. Over the years I've also grown quite insecure about it and anxious.
Now I also happen to not like alcohol or smoking which really reduces my chances of meeting someone my age to 0, because I don't go out to parties and such. Not that it was even possible during COVID-19.
I'm happy that I at least have supportive parents, siblings and family. But I think there are a lot of young people in my situation and many of them only have parasocial relationships, for example with Twitch streamers and YouTubers.
Homeoffice has been hard with all the distractions home has to offer and I really do miss eating lunch with coworkers. I'm going to start studying at university this fall so I'm optimistic that I might make some friends there.
