I hope you have the physical check-ups done and are taking treatment. However, the signs do indicate fears and anxiety. Our mind and body are connected; fear and worry increase the stress that can impact or trigger digestive, respiratory, or other physical illnesses.
Next Steps
I suggest that you continue the medical treatment with your doctor, but to deal with your fears and stress, start seeing a psychologist for psychotherapy(talk therapy).
Health Tips
Remember, our mental health is just as important (if not more) than our physical health, and ongoing stress can harm both physical health and overall quality of life. All the best.
