Even in the darkess hours I have never known depression. But I have seen it at work. I have the opposite problem with anger control when things go badly. I also relate to your feeling on killing animals. I gave up boxing when I had my opponite cut and bleeding. I could not hit him anymore.My friend Jim is a hunter. He was a Cougar guide. Gave me a free five hundred dollar hunt. The Cougar was in a tree. I literally said call the dogs off. No way I can pull a trigger. But I know about your migraines. Wife suffered from them for years and with them the depression. So I do as you know my friend feel your pain./dandy
