Do I have a Gemini Stellium *and* a Cancer one? Is it rare and what does it mean for my personality?

Here’s my chart... I’ve been called emotional and way too sensitive many times in my life, and I personally feel like that too. I think my chart has a Gemini stellium, but I’m figuring out stelliums and not really sure. And I’ve also seen that 3 planets in a sign also qualifies as a stellium- which would mean I’ve got a double: one in Gemini and one in Cancer.

Are stelliums (and double stelliums) rare? Do any of these explain my excessive sensitivity to emotional situations?
