Nothing will prepare you for this and having lost my parents a month from each other and my husband I can only say that nothing that people will say will make you feel better, but the only thing is to hold on to memories and God and not go the what if road, And give yourself time to heal... there is no time limit for feeling sad. I wish I had some wise words, because it sucks, all I can say is I am so sorry and I will hold you all in my prayers.
