cadent

The third house is a cadent house.Its natural sign ruler is Gemini and its natural planetary ruler is Mercury.

（属于变动，守护星座是双子座，主星为水星。

I figured if I could get that T-square in Cadent houses instead, it would be weakened.But that would also weaken the Sun and I didn't want to risk health.What to do?

我的本命上月亮巨蟹（发疯、忧郁症）我非常恐慌，我想如果让t角Cadent会好一些，但是这会使太阳力量减弱，我也不想拿健康冒险，我该怎么办？
