What causes atrial fibrillation? Is stress the main cause of atrial fibrillation, and is it genetic?

In brief: Not Really

The main cause in ~90% of cases from young persons like you is extra heartbeats starting in structures called the pulmonary veins.
Sometimes that's all it is; more often than not though, the top chambers (atria) also have dilation and scar tissue which helps sustain the fib once it starts. Only a small portion of afib is clearly known to be genetic. Stress triggers extra htbeats -?-> fib.

In brief: Many causes

The main causes of af are: hypertension, alcohol excess, rheumatic heart disease with mitral stenosis, mitral valve prolapse with regurgitation, coronary artery disease, aging, hypertrophic cardiomyopathy, lung disease, thyroid hormone excess, idiopathic (no identifiable cause), and rare causes.
It can run in families but is not predictably genetic. Stress is actually only a minor factor.

In brief: Stress

Stress can contribute to high blood pressure, so it certainly is a factor for some people.
A stressful event can also trigger an episode of atrial fibrillation in people who already have the condition. Research suggests that there is a genetic contribution to the development of atrial fibrillation, but the genetics are complicated and the syndrome is not inherited in a traditional sense.
