Well....My Mom has taken valium for years and has severe anxiety and rage issues as does my brother. All three of us shake when nervous or angry. I think my grandfather may have had PTSD from the war and was also a raging alcoholic. I have 8 uncles on my mothers side and they all have alcohol issues...all of them. I have two aunts on my fathers side that have been hospitalized for depression too. Wow....that is a lot of people in my family.
