It's very early days Steve and your emotions are raw and very near the surface, but given time you will be able to look through Jane's things and maybe smile at the memories they evoke.  It will never be easy but hopefully bearable.  Let the healing take place first and then maybe the "Life and Times" of Jane can be something that brings you joy rather than sorrow.

I think it is good that you have young people i.e. Caitlin and Tessa in your life as they will probably have a different perspective and will no doubt help you to focus on the future as well as having an interested in the past.
