I'm so sorry you're on the downward side again. It's such a difficult place to be. But it's OK that you are there. You will work your way through this, even if it takes baby steps. I am so glad you are seeing your doctor again tomorrow. You MUST trust yourself and your doctors; you can deal with the family later on. Many people who have not experienced what you are experiencing just don't know how hard it can be to find firm footing again.
Take care, and please update us again after your doctor's appointment. Be very honest while you're there about everything you've experienced in the last few days, so the doctor has the true picture of the situation, OK?
