thus far in my life, I have been 'diagnosed' by various people (none of whom are professionals) with the following:
Bipolar disorder (or whatever it is called; I'm not entirely sure of the proper names for any of these)
And some others I've forgotten.
None of which do I have. It never ceases to amuse me when people think there's actually something wrong with me. Sorry, folks. While a bit eccentric, I'm hardly mentally ill.
