Do you have rivalry with your siblings and can you explain it astrologically?

My mom and I have a difficult relationship! She and I are both Aries sun people, but while she has her judgmental Libra moon, I'm more laid back with my Taurus one. She has a Taurus rising and is stuffy and uptight whereas my Gemini rising gets on her nerves because I'm never focused on any one thing. We heads CONSTANTLY.
