I haven't rested since 3 nights, I still yawn, yawning keeps me awake. As soon as I fall resting, I yawn and wake up. How long will it take? I'm exhausted and frustrated. Can you see my eyes they are swollen and I have dark circles under my eyes. My eyes are b l 0 0 d s h o t and tired. I just yawn and yawn nonstop.
