Existential angst for me,even as a child.there are four basic personality types and I definitely fall in2 the worrier catagory.only some people have it so severe that it envelops every aspect of their lives.It doesnt matter about childhood issues,provided you wernt abused etc.I had and have wonderful parents.it sucks that it came out in the wash the way it did;an eternal search for meaning in life;every tiny aspect of it.according to homeschooled on this forum,illness can be neurologically based influencing your thoughts and hence feelings.Its an interesting and tempting theory.what you think?
