Very courageous of you to share this... I can certainly relate.  I feel like I have all the 'tools' in my toolbox to theoretically help me reconstruct my life, but somehow, I just don't utilize them very often.  It seems so overwhelming at times.  I keep reading inspirational books, and seeking out inspirational wisdom online, and I hope it will help by osmosis, but it just doesn't.  I end up overtired and unenergized.  However, I think I'm making some small steps forward.  

Bottom line is, you need to give yourself time to heal.  You have been through so many life-altering crises, in a short period of time.  Even though you're making a conscious effort to change your thoughts to 'forward thinking', which is awesome, it's going to take your body time to catch up.  Keep thinking those positive thoughts, and you will create a new reality for yourself.  There is, however, a lag time, for your physical reality to catch up with your thoughts.  Keep faith and believe that change is imminent, and already on its way (as in the message of "The Secret").  The vision board will help with this too!  Other suggestions are to join a women's prayer/meditation group, and to join a support group for separated/divorced men and women.  I've recently done so, and am really enjoying it.
