Tough spot. What you need to do is hold in your emotions till after your exam. Ball it up after you ace this test, then afterwards, break down. Fall down hard. Then you need to rebuild yourself. Think long and hard about what he gave you, what you need from him, and how it can be replaced (this doen't mean jumping to another guy). Just learn to get by and re-emerge in the world as a stronger, more confident person.
