I am no psychiatrist but mine told me something simple that surprised me.  Most of us avoid sorrow, avoid experiencing it; its not something we want or want to admit is there.  Its something each of us as individuals must adapt to and process and that for now, I believe is our test.  Trying to figure out how to incorporate it in our day to day lives and not deny its existence; that can be even more emotionally exhausting!  I hope there is joy around the corner for you darling!
