If you are absolutely sure you don't identify with virgo, critical, analytical, trying to heal yourself and others, then consider you might be before virgo - leo, or after - libra.
Ive been unsure about my rising. Im a pisces with virgo rising. I have very strong virgo characteristics and can really identify with virgo. However, I also really identify with leo. I wonder about other elements in my chart, and after doing some vedic astrology I have discoverd I'm the sign of the sun - leo. Which would explain my multi personality. ITs hard.. but i think a good astrologer can help.
