You should take medications, you should really. They are no exact science, but they may work, it's worth to give them a chance. I mentioned the mood stabilizer, but of course it would take an expert psychiatrist to evaluate your condition and prescribe accordingly.

And let me say a totally offtopic thing: by that small webcam snapshot I can spot a really cute girl :-)
Too bad I lev in Italy, if we were near I would invite you to a photoshooting (I am a photographer) to catch the sweetness in your eyes.

The best of luck
