Bottom line, none of this would have happened if you weren't drinking. You can't blame your then girlfriend for what happened later in the year. If you want to stick to your "theory" of if she would have been supportive you wouldn't have had a seizure, you could also say that you are responsible for choosing someone in your life who wasn't supportive/knowledgeable. I wouldn't get into the blame game. It is counter productive. We are responsible for our choices.
