As far as the breathing difficulty, it’s called dyspnea.

Dyspnea is just a fancy Latin word used by doctors, and it means shortness of breath. It can be brought on by all kinds of things--COPD, allergies, asthma, exertion, etc. It is a symptom of something bigger. The key is to find the cause, not just treat the symptom, though treating the symptom is important because it can be serious when you can't seem to catch your breath.
