So upset about the London concert

I took extra medication for trauma induced Schizophrenia I suffer and halfway through the concert I passed out and I am devastated because I have been waiting since I was 13 (im 27 now) to see him and I have his face tattooed on my arm and this was meant to be the best day of my life. What do I do because I'm so devastated. I just wanna cry all the time for this stupid illness and how I'm so stupid for passing out.
