I am fairly controlled in crying in front of people as I know it makes many people uncomfortable and do not want to do this.
I did have problems however when two of my children died at for a long time then I would burst out crying with no warning -I would normally take myself out of a social situation when this happened as it gets worse for me when someone then comes and hugs me which people seem to do -I then totally lose control.
Nowadays I can control my grief and tears as am home alone a lot, and yes, it does still happen to me, just not as strong or uncontrolled.
