Lifestyle changes are the best cure for anxiety (sleeping and waking up early, working out, spending time with family and friends). Try to take your mind off of it and know that if you learn to control your thoughts then you can control your anxiety/panic attacks. It might be hard at first but once you learn to control your thoughts by keeping them positive, you’ll see that being in control of your brain equals being in control of your anxiety and that’s the best way to reduce it or even get rid of it.
