I too am very sorry for your loss, and clearly remember my (almost) hysterical bouts of crying when my husband died.
We all tackle grief in our own way, and should do so, but I found it helpful to get on with practical things, sorting my husband's clothes, putting aside personal possessions for our son, going through papers for probate, and in between practical tasks allowing myself to cry.
This may not work for you.
Any bland oinment applied under your eyes and on your cheeks shouldl help the discomfort from weeping, and a mild saline solution to bathe your eyes with ought to help too.
