Thanks so much to all of you for such a warm welcome!
I've actually got a bit of a headache, so I'm going to stop researching for a while (due to my family's strange schedule it's more like 4pm for me, even though the clock reads 8-something where I live). I'm trying to make myself take it easy, so I'll probably reply more tomorrow.
Thanks again for everything - I'm feeling more confident in my ability to face all of these issues since this seems like a wonderfully supportive place.
Have a good night everyone!
