My anxiety levels were sky high after coping with too much over a few years. Its manifested itself and heavy duty anxiety to the result I even went to Drs who got me on a self help course for it. All well and good but it just gave me all those well worn things that you know all about when you are feeling fine but they go out of the window when you are all het up and anxious.
The one thing that does work for me, and its an effort to do but always works. Whatever the weather - get all the right gear on, wellies, waterproofs etc etc and one mad dog that needs long walks. Go for said walk in the rain, watch daft dog run into hedges, sniffing rabbit burrows and running around in circles. Result is we are both worn out but get fresh air, excersise, work up an appetite AND get a better nights sleep.
