Hey I have no clue how to start this off but my names <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> I’m 13 years old and I’m currently being tested for heart disease and I am absolutely terrified because like if I do end up having it this affects my full life I want to join the Royal Air Force which is a career u need to be fit for and I can hardly get through a hour PE session without nearly collapsing I just want some advice on how to handle this since I’m still fairly young
