I want to comfort you, but I'm afraid you'll laugh.

Then find a place where no one is around, and cry when no one is around, but try not to go to public places, which is not safe. Maybe you have been wronged. You are tired. Talk to friends.

Then don't care too much about face. Holding back is not good for your health. It is normal for people to cry, because people are emotional animals. There is no need to be shy.
