When you are alone, you can let the emotional wave pass over you. When you surrender to it, you will feel intense, overwhelming emotion. It can feel like you’re going to die in the next instant, and you are disappointed when the releif doesn’t come.
The emotion will hold your body and mind as long as it can, then it must pass.
Luckily, the mind cannot maintain a state of pure emotion for an extended period of time, and the all-encompassing despair and emptiness will fade for a moment, until the emotions well up inside you again, demanding to be released.
During the overwhelming moments of despair, remember that the feeling will pass, and you will get through it.
