I would say its clearly not normal....I'm nit sure why the professionals you've been
in contact with think it is normal. I've had the symptoms you've had, not for three months
and not with the sexual component, but I've always understood my symptoms to be
of a hypomanic nature.
I do feel the need to point out that at this time I am unaware of my official dx.
The first psychiatrist I ever saw put in my file that I am bipolar but I've since seen
two others shrinks and I'm not current with what my current doc thinks.

Are you being treated in any way for any of your symptoms?
