burned out

i keep gaining weight.  I can't sleep.  I'm drinking too many liquids.  And I can't stop thinking about my friend , Wanda, who died two ...or is it 3 weeks ago.  She's been on my mind so much lately.  People keep say,"she's in a better place" or "she's not suffering anymore."  i wish I knew if that were really true.  She did not make a proffesion of faith before I left her when I tried to talk to her about it only 12 hours before.  And I don't know what happened after I left.  It's been eating me alive.  I hope.  I hope.
 
And I just can't seen to get me togther after that.  My doctor has seen alot of me since then.  I am truely stressed out.
