Hypersexuality and overspending usually come when we lose touch with reality. Hypersexuality results in having sex with people without thinking about the consequences, if one is in a relationship - having affairs. Not using protection...

I don't overspend as I tend to quite stringent with my money anyway, but I do notice myself buying one or two things I don't really need, or just because "they're NICE". Usually I have to justify to myself why I buy something to the n-th degree.

I do not experience Mania, and I do know what it is, as I've seen my best friend go through it. I just have slight hypomania.

There are plenty of links on the internet to learn more, but I just read until I understood the basics. Now on PC I feel I have a support structure and can discuss personal experiences with people. We all have some symptoms that may not be stereotypical, but 99% of the time you can be guaranteed that someone on here has gone through the same things before you.
On the top of this page there is a link to some info too.

I've recently started using the mood tracker (Under QUIZZES above) and I hope it gives me a better understanding of myself. If you have the time and emotional strength, I'd recommend keeping a diary to write your thoughts and feelings down. Try understand the length of your cycles, to help you know what to expect.

I'd also go and see a doctor to make a diganosis - form the above I assume you're not yet one meds? This is VERY important, as it will definitely improve your quality of life.

I spend most of my time in depressed episode or mixed.
