What does it mean if it feels like I can't breathe right?
I'm 18, and this has been going on for almost a year now. I AM breathing, the doctors said that I am getting enough air into my lungs, but it's hard to get a deep breath in. When I try to breathe a deep breath, I have to move/stretch or even sometimes fake yawn. So it constantly looks like I'm tired because I'm yawning every 5 minutes. It just feels like there is a heavy weight on my chest or someone is sitting on it. I've researched anxiety/panic disorders but doesn't that happen when you feel stressed out? I feel like this 24/7, I don't think it's possible for someone to feel stressed out everyday for almost a year (it will be a year in April). Can someone please give me an answer or give me a link to a website that will help me figure this all out, I really don't want to go to the hospital again. THANKS!
ps; this all started to happen when I was in my grandma and grandpas very small attic, so I don't know if that has some affect on how this all began.
