Sun, rising, moon, venus and mercury in same sign

Hello all! I'm a Ram/Aries, my rising sign is aries, moon in aries, venus in aries and mercury in aries.
Is anybody there in the same situation? Does anyone knows how much does that affect you?

I'm a Cancer Sun, Moon, Rising, and Mercury (but Venus is in Gemini)...
Are your planets in the first house or twelfth? That will also affect you.
