This is something I have struggled with in my past relationships. My last partner equated my love / passion to a blow torch. It's accurate too. I don't hold back when I fall for someone. I have trouble articulating sometimes about how I feel and so the vibe when I go inside myself to search is a bit jarring. I've had partners who say it's like they can hear my head vibrating in thought.
I don't think it's possible to feel too much. I think it's a beautiful thing to be able to feel, even when I am in extreme emotional pain. I think to myself "what a gift to love like this".
