My heart just broke

Seven weeks!  I don' know how to help myself.  This is bad.  I am worse today.  I am doing the right things like support group, prayer. I've lost my best friend, husband.  We were kind of loners and were there for each other.  I need him. I am so scared.  I have grown children and am trying to let their lives go to a more normal frame.  I dont't want to call them every day crying.  We were married 15 years.  I am thankfull for those.  I just want more.  He was a rock for me.
