Maybe empathy is not the right word. Whatever it is is the result of heightened emotions. I try to not worry about it too much and remind myself constantly that I'm actually very lucky, because I live in a relatively stable environment and am surrounded by supportive people. The best advice I've gotten, that's helped, is that I just need to familiarize myself with myself and with that comes control. It's exciting to hear what you're working on though, in hopes that it will help people down the road. It's probably not the easiest job, but it's good to know there are people out there trying to tackle the problem. It's also good to see over the years the heightened public discourse on brain injuries and how they can affect people. Maybe it'll encourage some to make healthier decisions and take less risks.
