You live with your dog and your mother, do you not? Many say that we select our parents before birth.
It is indeed possible that service to your mother is a large part of your incarnative path. And, as always, we also select lessons for ourselves along the way. And as you also mention, you may serve simply by carrying a light vibration. A lighter vibration radiates a large energy field, affecting many seen and unseen things around you, and that in and of itself is a service.
I would say that the key to discovering your selected path of service is that there seems to be a correlation in learning one's own incarnative lesson and in finding your path of service. Discover and balance yourself, and in the process, I would be surprised if you did not find what you are seeking.
