This year has been incredibly hard for everyone. Before 2020, you'd have gone on nights out or other socialising with your cohort. With the pandemic it's been hard for everyone. S
You're absolutely not doing anything wrong at all so please don't think that 😊
Once everywhere starts opening properly you'll be able to get out and meet people and make more friends. Also, don't wait for an invitation, be the instigator and invite people out or approach them. Take control. I'm sure you'll make lots of friends when we get some sense of normality back. 😊 Good luck.
