Could there be mold in my house if every time I am home for any length of time I am short of breath and feel aloof?

Short of breath. It very well be something in your home you are reacting to. It could be mold, or something you are allergic to e.g. House dust, mites, or some chemical you are reacting to. Animals in the home can also cause allergy and problems with irritattion of the lungs. You could have low grade asthma. You may have a toxic home. You need medical attention to find out why you are short of breath.
