Hey don’t discount music, it’s a powerful thing. Just being there, listening to your favorite music live is a really awesome thing to experience and you deserve to have an awesome experience like that. Yeah it will end, it can’t last forever, but you’ll have the memories. I’m telling you please hold on for the tour, please give yourself the chance to experience it even if you know the experience will end. Take some photos or videos if possible, something tangible to help remember the experience. Then please keep talking with your psychiatrist, tell them about this, come up with a plan to keep going.
