Why am I constantly yawning

Hi I am a 15 year old who does judo so i am pretty active but I realize that I am constantly yawning and my heart is racing all the time. I have recently move houses and i found that mold was in my room after about 7 months of staying in there. I have been doing some research and it showed that mold can cause asthma so i thought i had asthma but i am very scared to go to the doctor because i hate needles and those things and just hope that it is not cancer or anything. I have been having this problem for the last 3 years but it wasn't that bad actually it seemed like it went away and now it back. I have moved out of my room so I am wondering what is wrong with me

THE TRUTH IS that we don’t completely understand why people, or animals for that matter, yawn.

It’s widely assumed that yawning occurs because we are tired or bored or because we see someone else doing it, but there isn’t any hard evidence to support these beliefs.

Scientists do not purport to know all of the biological mechanisms of the yawn, but tend to agree that a yawn is an involuntary respiratory reflex, which regulates the carbon dioxide and oxygen levels in the blood.

Technically, a yawn is the reflex opening of the mouth followed by the deep inhalation and slow exhalation of oxygen.

The very act of yawning is but one of a number of involuntary reflexes controlled by the spinal and nerve centers.

Scientists speculate that the onset of a yawn is triggered either by fatigue, or by sheer boredom as, at those times, breathing is shallow, and little oxygen is carried to the lungs by the oxygen-toting cardiovascular system.

When one yawns, his or her alertness is heightened, as the sudden intake of oxygen increases the heart rate, rids the lungs and the bloodstream of the carbon dioxide buildup, and forces oxygen through blood vessels in the brain, while restoring normal breathing and ventilating the lungs.

This quite plausible theory of yawning falls short of explaining many aspects of yawning. Scientists explain away the "contagious" nature of yawning, that is when one person's yawn triggers another nearby to yawn, as due to the power of suggestion, but are at a loss when attempting to explain why yawning occurs excessively in patients with lower brainstem damage or with multiple sclerosis.

Other unlocked mysteries include why fetuses in the womb yawn, when it is a well-known fact that they do not intake oxygen into their lungs until after live birth, or why individuals with high concentrations of oxygen in their blood streams yawn.

Until these questions are answered, do not assume that a person who yawns in your presence is bored with what you are saying, or suffers from exhaustion. Simply be pleased that he or she is not bored to death.

I have been researching why I have been feeling like I have to yawn so much and also feel short of breath. It feels like a panic attack, but I'm not panicking until I just can't seem to feel like I can catch my breath. Here is a link to something I found that has alot of different answers. I am hypothyroid, and I believe that is what is causing it for me.
