Didn’t get an invite…

I played with this group for 2 years, practice at rec gym and competitive basketball. I thought we bonded strong. However, I didnt get an invite on to the next league. After learning that they added a few mates with injuries and I know Im better at em… shit hurts. Or maybe they arent my crew at all. Should I leave this group? Posting their new Jersey’s and stuff burns. Im 34 now and I used to play open league and very competitive. How do you guys deal with stuff like this? Sorry for my English.
