Mermaid, we create attachments and sometimes there is no obvious explanation but when there is a break up and severance of important relationships, we are put through the paces of grief. Explore your heart and mind. Take inventory of your relationships and your life and look for the common threads for answers.
There is an article about Complicated Grief and a Grief quiz on Psych Central. Very useful. You may not have realized that you are experiencing a "loss" in every sense of the word and need to grieve.
