@Iarlaitha - I've had some struggles with fear and anxiety in the past, including panic attacks. A few months of talk therapy helped me through a particularly rough patch, but I've also discovered that I need to take care of the underlying negative emotions that bring those states about.
Meditation and reflection can be great for this. I've also found a lot of relief using EFT or Tapping. Basically Tapping is a way of releasing negative energy that's stored in your body. If you're interested, I wrote a post about it here:
