I also think that holding back emotions in oneself is harmful. The main thing is not to turn it into an eternal drama and cry over any nonsense. There is nothing to be afraid of, every person has their own feelings, everyone experiences them in their own way.
P.S. The main thing is without fanaticism.
Tears are a sign of an "overflowing bowl" of emotions that excite you. Those emotions that give a sharp signal to your brain, that is, which are important to you. Therefore, holding back such emotions is "unhealthy".
