An emotional dive or jump is understandable. I have a family member who battles depression and everyday he works at it. He has many good days and some not so good. Good luck, but IMHO your stories that you share(especially the humorous ones) shows us that you are dealing just fine. There's something incredible about seeing and doing all that you've done and then be able to see everyday life way more clearer than the average person.
