Cold showers. Within a lifetime of problematic anxiety, I can't believe it's taken me this long (to my mid 40s) to discover them. Actual game changer.
If you have trouble with anxiety and panic, and haven't already tried cold showers, try them. A cold shower can bring me back from crisis point to feeling quite fine in about 2 minutes, sometimes. The effects can last for hours. And when they wear off... you can have another.
AIBU to think GPs should give this as an intervention before drugs?!
