Do you have a person in your life whom you cannot get away from, and who draws all the (little) happiness you may have out of you?

The 'dementor' effect, Mr Mechanic calls it.

He has one.

I have one or two.

You start well, and life looks reasonable. You have pep-talked yourself into having a good day.

The 'dementor' walks in, or emails, or calls.

You are left feeling empty and sad.

Does anybody else have one of those?
