I had a very bad accident a few years ago - almost ended my life. It seems ever since my whole perception of life has changed. I just don't care anymore, and I do go through bouts of depression, negativity, etc. Its very odd why I feel this way, but I try to manage... don't like taking pills, and never will.
Like the previous poster I too go through panic attacks and feel like letting out a scream more than once and a while...
