This Isn't Anything New. For As Long As I Can

This isn't anything new. For as long as I can remember I have always felt congested. I have to constantly cough to clear my throat from mucus and my voice sounds scratchy or hoarse most of the time. When I lay down, I can't breathe at all from my nose. I have dogs and cats and mold tends to grow in my house. I have unatural dark circles and get headaches when it feels worse.
