I got "selected" for Jury Duty....What should I do?

lol, I received a letter informing me that I won a million dollars I was selected for Jury Duty
Now it sounds really interesting seriously and I would like to do it,
BUT I don’t know if I should because of mental health issues because I’m sure they don’t want “crazy” people on the jury….
what if I don’t tell them about my Mental illness, and want to do it
what should I do??? What would you do??
