>It isn’t enough to rely on random invites. Get your calendar out and map out your social life. Make sure your week is scattered with social activities.
This is the worst advice possible. I did this when I was a freshman at uni. Just saying yes to every invitation. Disco, birthday party, cinema, whatever. I thought it'd reduce the loneliness. But I never ever enjoyed it, and I felt lonelier than ever before. Then, at some point, I got a tinnitus from a disco visit. It's not loud, luckily, and I can barely make it out throughout the day, but it's there. But that was when everything changed. I started saying no to everything. Now, I maintain very few relationships but they're much deeper. And I'm happier like that. Don't ever say yes to things that don't feel right.
