I am having difficulty following your request. You have been suffering from a bipolar disorder for 9 years. You say your manic phases are not too intense, just some hallucinations and delusions. I don't understand the connection of your manic phases and the guy in the band or the rejection you feel from his famous friends. I understand that this is the last tour for the band and that has changed something in you in a profound way. You become aware of different levels to your mania and that this is the last year of your life. This does not make sense when you say the last time you wee in a concert was five years ago. My only guess is that since you are bipolar you are starting to realize that you are in a manic phase where time and space seem more plastic and malleable then when you are depressed. If so you are realizing that you need some help and I would suggest you try to get it soon. You are in need of a change in medication or at least a psychiatric evaluation .
