I am sorry to hear about these troubling symptoms. I encourage you to arrange to see a pediatrician

A myocardial infarction, or heart attack, occurs when a cholesterol plaque in your coronary arteries fractures, leading to a blood clot. Patients often experience chest pain that can radiate to their arm or jaw. They often also note shortness of breath, sweatiness, nausea, and vomiting
. Risk factors for this include age, male gender, smoking, high cholesterol, and high blood pressure
. It is very rare for someone your age to suffer a myocardial infarction. However, it can occur in certain genetic conditions and in those suffering from certain autoimmune disorders. I strongly encourage you to discuss this with a pediatrician.
The shoulder pain may be a separate issue, especially as it has occurred more recently. Possibilities include a bone fracture, muscle damage, damage to the cartilage lining the shoulder joint, as well as tendon or ligament damage.
It is also possible that your anxiety disorder is contributing to your symptoms. However, you will need a thorough history, physical exam, and EKG performed by a pediatrician to evaluate your symptoms.
