SIX air signs in my chart?? (AND Gemini rising...?)?

Your friend is not correct about the mental illness part as far as the information available. But to not use your question and rambling as an answer to such is just not fair and is irresistable! There you are! Always thinking, always talking, spreading your thoughts through the air, that's the essence of all that air. But don't despair you have earth grounding you, water to feel, and fire to motivate you. Why not go the rest of the way and get your entire natal chart and read about yourself through the planets in houses and signs and the aspects between the planets? You'll be pleasantly surprised at the amount of information. And you might even find it makes a good investment. I like cafeastrology.com
