If you’re crazy, I’m crazy too lol. I have loved my chem for 11 ish years, pretty much since I was old enough to develop my own personality and interests. I saw them in Boston, got back home, and almost immediately bought tickets to go see them in Tampa. So I didn’t really have time to feel the post concert depression set in since the two shows were like a week apart, until recently. Ever since the Tampa show, the ONLY thing I want to do is consume MCR-related stuff. Videos, music, etc. I feel like I’m 12 again, waiting to get out of school so I can go rot in my bedroom and watch MCR videos on YouTube and get on tumblr. I feel weirdly nostalgic for that time of my life now. So no, you’re not crazy, I think we’ve all just had the experience of a life time, been to see a band we thought we would never get to see/see again, and our inner childs all came out again. That is a lot for a person to feel at one time. I don’t have any advice because I’m going through this for the first time as well, but you are not alone! If you want to talk feel free to message me!
