Merry Meet PhoenixRavan,
First, are your convulsions causing you pain? Do they make it difficult to breathe....does it endanger you in any way? If it does, I would take the mundane possibility to a doctor. It's your body and you have only one. Second, where does energy comes from? How does it relate to your own body? Do you know about the human energy system? Do you know about the chakra energy system? Do you know about grounding and centering? Do you know about shielding? As a sensitive being, these are all questions you must find an answer to, by doing your own research, via books, courses, and within as well.
Sorry there are no easy answers here, but maybe the thrilling call for exploration!
