I have a constant stuffy nose, chesty cough that makes me heeve when i cough too hard, buzzing ears and i feel as though my throat is closing up and i cant breath as good. I think it maybe my hayfever, or i have allergies? which i take tablets for. I dont go out that much, and i dont sleep until early hours in the morning.. could i have depression also? Lastnight, i woke up as though i had been holding my breath or something... it really scared me. Please help!
