Vicki, I am so sorry for the loss of your daughter.  Especially during a time that is usually a joyous event.  My son left us a 21 month old granddaughter and it can be so bittersweet.  This time in the beginning is indescribable.  You go through so many emotions.  I had those same problems as you when I would go places I had been with my son, or if I looked in the cabinet and saw something that he liked to eat.  So many things will trigger the loss and our pain.  I can only say to go through it minute by minute, hour by hour, and day by day, as I'm sure that is what you are doing.  You have a long road ahead, but the uncontrollable outbursts will gradually lessen.  I'm not quite a year into it, but I don't believe it ever goes away completely - just gets less and less severe.  Let out your feelings, do whatever you feel the need to do.  You need to allow yourself to go through it all.  Come here to the site when you feel the need to express yourself, and try to take care of yourself.  Hugs & blessings, Ann
