My advise is to allow yourself to cry as often as you need to. It will get better with time. Also remember that whatever bad thoughts are in your head, they are just thoughts and can't hurt you unless you act on them. I found that writing about my thoughts helped, as does talking with other support people, like a therapist or other members of this forum. It helps get it out of our heads and out into the open so that we may begin to heal. I cried so much I literally thought I would die from the grief, but I didn't. Now I seldom cry and when I do, it doesn't last long. Allow yourself some time to laugh and play, it is difficult moving through certain healing phases and you owe it to yourself to be gentle and understanding with yourself.
