I added the red emphasis.

If you don't mind me saying so, please see a doctor/medical emergency staff if you haven't already. Then check the great forum Rae's linked you to & settle in wherever you're comfy.

Sure glad you're here! I look forward to getting to know you when you're feeling better. Keep asking questions!!
