Social situations that are physically draining help?

[Truthful Alibi]

Everyone at school was crying today because it's nearly the end of term (which is tomorrow) and not only could I not cry, but my body felt exhausted and I felt sick (as in nausea, not illness) because everyone was crying. I managed to hug some people though, which I normally can't do.

Anyway, tomorrow is the last day, so it'll be even worse, so how do I survive all the crying? It feels like it drains me. Other people have commented about this, but, for me, because of the crying, it's worse, and since everyone will be crying, I won't be able to escape, so how do I deal with this?
