I agree with gRAVVY. t's also good to think of it in such terms. Stress is often seen as a general trigger for most of the otherwise biologically based psychiatric disorders. we just don't handle it well. It causes all sorts of funky things to happen to the body and to the chemistry, not to mention the brain and the thoughts. So yep, people, situations, lack of sleep, memories, all that can cause a lot of stress and trigger an episode. Most things about people have a rhyme and a reason, but not always easily seen or open to be dissected. Hugggssss!
