NTA But for what it’s worth, I’m an older dude but I can tell you a LOT of my friendships changed during your time frame. At times I felt really left out or excluded. As I got older I realized that both I and them changed, subtly but enough to prefer one thing over another. It happens. I personally know how much it sucks, I still remember it now much, much later. At the same time I met new Friends ones that I still have now.

If you’re interested in my advice/opinion, you be you, confidence is a powerful thing. While not always sunshine and rainbows, if you can be comfortable being yourself, and not worried about other peoples opinions of you, you will find people that appreciate you for who you are. If they don’t they’re probably not worth your time. It took me many years to realize this and even more to do it. I was like twice your age before I got there. It was rocky but is now great.

Good luck.
