How can you deal with panic attacks without medication?

This may be discovered through trial and error with yourself, but there are a variety of tools that people find helpful such as counting techniques, holding grounding objects, breathing exercises, showers, touch from another, etc. I would look into DBT skill building and build a plan that works best for you. If you have a mental health provider, state that you would like to build a plan together for when you start to feel one coming on.
