I'm on Christmas break right now, but I'm not doing well mentally. My therapist is concerned about my mental state right now; she says I'm experiencing psychosis.

If this keeps up, I'm going to have some kind of mental breakdown at work. Or I'm going to completely lose touch with reality, if I am indeed experiencing psychosis.

What are my rights for taking sick leave? Can I bring in a dr's note for short-term disability? How does short-term disability work when it comes to this stuff? Does it cover chronic conditions like BP?
