Depresssion: loss of job and husband with 1 year of each other

Depression:  with the loss of my job and my husband within one year of each other.
I think I am suffering from depression because of the above.  I have not seen a doctor about it but I think its what I got.  I get mad for silly reasons.  I don't want to leave my place but I do have family, friends and boyfriend who get me out of my place.  Its funny how I met the boyfriend through a friend.  When I babysit or by myself, the blackness just engulfs my soul and spirit.  Watching Tyson certainly helps me feel less overwhelmed by the blackness.  Does anyone else suffer from depression after the loss of your spouse or loved one?  I am just curious.  From Diane B.
