The most common advice I receive for my anxiety generally stems back to distractions. In order to help stress and overthinking, you have to occupy your mind through essentially anything that will bring your focus from the "what if's". Meaning it's helpful to find a hobby or things you love that allows you to channel nervous energy, otherwise it's easy to become more stressed. Activities that stimulate and hold attention work best and are valuable tools to distract from the uncomfortable sensation that accompanies anxiety - whether mental or physical.

It's extremely easy for someone with anxiety to become obsessed about how they feel in these instances - it's not fun and it's a rough cycle. However, the less preoccupied you allow yourself to be, the less opportunity to obsess over the anxious symptoms. So finding something that you enjoy that holds your attention is a good way to distract from constantly assessing the anxiety.
