I can only answer that last part: doctors have seen many, many patients break down in front of them, I guarantee. You have a lot going on in your life right now, and your doctor isn't going to judge you for breaking down under all that stress any more than one of us would. If she's worth her salt, and it sure sounds as if she is, then she won't respect you any less for it.

Besides, I'm sure doctors would rather have a patient who tells them everything (whether in an emotional state or not) than a patient who plays tough (and thus, withholds key information). If you think about it, you're actually making her job easier by informing her of all the stressors in your life!

I hope things get easier for you. I wish I could answer your other questions, but I'm sure there are some knowledgeable folks here who can do that. :)
