Depends. Don’t cry in public, but it’s ok to cry sometimes. I rarely do, but I did cry when my father died less than a month after my 19th birthday, and I also occasionally cry when my sleep has been so bad for days it’s literally killing me. A month ago, I could only sleep 4 hours one day. The next day, the neighbors were doing construction work all day and the noise kept me awake after just 3 hours sleep. Then the next day, I couldn’t sleep at all because my body was so full of stress and I had an early in the day appointment. It broke me and I just laid on the floor wishing to die
