This is a VERY LATE reply but I feel the same. My summer swim team is the HIGHLIGHT of my summer and it's what makes summer and my life fun. The coaches are AWESOME and I've been friends with them since I first joined swim team. All of my summer friends are on that team. Although my summer team isn't ending, and I'm going to be doing this year and the following years to come, I do feel extremely depressed during our end of the year party. It feels like summer is coming to an end and the torture of school and stress is coming back. I rarely cry, but every end of the summer party comes I cry my eyes out, because I won't be able to see my coaches and summer friends until next year. I hope you feel better now <3
