Dr. Beth, I am confused by some of the changes I am going through. I turned 50 last November and ever since then I feel somehow ungrounded, like I don’t know who I am or what my priorities are. They seem to be shifting dramatically. I used to be focused on being a parent and wanting to achieve a lot in my profession.  I did lots of extra work and participated in the executive boards of a couple of organizations.  Now I don’t seem to really care and I feel these commitments are obligations instead of enjoyable.  Any thoughts about what might be going on with me?
