Crying sessions?

At different points in my academic life, I have utterly and completely broken down and cried in front of almost all of my teachers/supervisors. I was thinking about it and as much as I say, it’s okay to be vulnerable, i felt a rush of embarrassment. I remember breaking down in front of all my classmates once and i was shouting and saying “I miss my mom”. I was in Europe and an international student. Now, one month into my PhD, I already cried in front of my supervisors.

It’s a bit embarrassing to think about it. I hated being vulnerable (at least this soon) in the PhD. I am just under so much pressure.
