Tiger, sorry you are suffering from anxiety. That is a heavy load to bear when trying to cope with life's stresses. Here is an article we discussed in anxiety support chat on Friday at 8PM EDT. How to Halt and Minimize Panic Attacks | Psych Central

This is how I practice lessing anxiety through relaxed and mindful breathing.
The first thing we talked about trying is an exercise to count the breath.
One on the inhale
Two on the exhale
normal breathing
Three on the inhale
Four on the exhale
continuing up to 10

Then go back to 1. Try this in the morning when you get up, during the day, or when you are trying to go to sleep.
