Hello, for the anxiety go to a private psychiatrist and for the heart problems thing try going to the hospital for a doctor (or group of doctors) to run some tests on you :) You can also eat the right amounts of food s (if you get what I am coming from )
Dealing with anxiety - Take a time out - Eat well-balanced meals - Take deep breaths - Get enough sleep - Exercise daily to help you feel good and maintain your health - Limit alcohol and caffeine, which can trigger anxiety and panic attacks.
Heart problems This can be a medical problem, in which doing daily things can help but not solve. I recommend visiting your doctor for this.
