To the shy, socially awkward teenagers during quarantine, what was it like coming out of COVID and re-entering society? (for a school project)

I was a pretty shy and awkward kid, and I was in quarantine for the first two years of my high school. I was confined in my home for two years, only ever talking to my family and siblings (which might be even more than other people had). Coming out of that, I had difficulty making friends and forging connections. Some of the students had been attending my high school in-person for a while now, so they had already formed friend groups and such. It was a struggle integrating myself into new spaces where everyone is already familiar with one another. Not only that, but I also struggled with my grades and keeping up with the coursework (especially when we first had online classes). I felt like I was behind on everything: socially and academically. Even when applying to colleges, I felt like I hadn't done enough nor have I experienced enough.

If anyone can relate, I'd appreciate if you would share some of your thoughts and experiences with me! Let me know how you felt, what you did, what you regret, etc. I think we could all somewhat relate to each other.
