Why is heart focus incompatible with my analytical personality and anxiety?

I find that traditional, passive focus on the heart center causes immediate anxiety and mental resistance. I feel like my personality is built for logic and action, not for soft emotional focus. My birth chart suggests a strong analytical temperament that struggles with the intangible. I need to know if my core personality structure is simply incompatible with this method, or if there is a modification I can use to bypass this block. My name is Rahul, born on 15th August, 1998.
