Breathless in Jersey

Since Monday I have been experiencing the worst shortness of breath yet. I called my lung doctor Tuesday and she had me go for a chest x ray (thinking that the fluid was already back.) I had to have someone drive me there as I couldn't make it into the building alone. They told me to go right home that my doctor would be calling me. When I arrived home the doctor called but told me although there was a small amount of fluid, there was a new pneumonia brewing. Thankfully we caught it early. She called in antibiotics for me and I am doing four nebulizer treatments each day as well. I had to crank up the oxygen a bit. If I sit perfectly still I am okay but the minute I move I can feel the difficulty I have breathing. I am so exasperated. I had an episode where I was going to go to the pharmacy alone and became overwhelmed with panic when I got in the car with the portable tank but couldn't catch my breath. Rob stayed home from work today to take me to the doctor's. I don't know what she will say or do. I just know that not being able to breathe has become a real source of anxiety. I hope to get some help/answers today. It finally stopped raining and perhaps if the humidity lowers that alone will make a difference.
