Download headspace meditation app. Pay the money. It’s worth the subscription. Can’t put a price on your (mental) health. Take the courses related to anxiety management.
Or learn to meditate without crutches like this. I've learned to not rely on something outside of myself for my own peace of mind. That's what meditation is about: getting to know your inner self and calling upon your inner calm to face difficult situations.
Why would you pay money for this? Literally just sit down and let your mind empty in a calm place. Just sit and be. Why does everybody groupthink and recommend a stupid app?
