@shoregal45 Have you checked about carbon monoxide poisoning? This is something that comes on very slowly. Do you have a carbon monoxide detector? If not, call your local fire department immediately and ask for a sniff down of the air to make sure you don't have this colorless odorless gas in your house. And yes, anxiety can certainly cause all the symptoms you have talked about, but you still need to make sure exactly what the cause is. Keep us posted, please. We care about you.
