Does anyone have tips for Post Concert Depression?

Hello all! I've never been to a concert before but I decided to go to the Dreamcatcher Seattle concert on November 13th. It was a ton of fun, even for someone like me who's pretty shy and not a fan of too much noise. Dreamcatcher was fantastic and the music was amazing as well. Jiu was already one of my favorite Kpop idols but after seeing her in person, she might be at the top lol. Also, the people there were great and very helpful, especially during the confusion of the M&G and 1:1 snapshots. One person even let me use their mobile charger, which if you're reading this, thank you so much!

However, it's been a few days and this feeling of emptiness and sadness has been sticking with me. I heard about post concert depression when I was planning my trip to the venue, but I was not expecting it to be so powerful lol. Did any of you guys have this issue? If you did, how long did it take for that feeling to go away? Or did you do anything to help alleviate the feeling? Thank you for any help!
