Mark,
another thought is that rather than "anxiety" it's stress - the two are so similar that I often wonder where 1 begins & the other starts, especially when I don't know the person.
Whatever it is try the following: take a gentle 30 minute walk between 6 & 7 am every morning as there's something in the sun's rays (& yes it still works when it's overcast!! Or drizzling!!) that works on a chemical in our brains at that time of day to help reduce stress. Another stress reducer is tryptophan (found in lots of things, plain yoghurt, bananas, most nuts, pumpkin seeds, turkey etc) this helps balance the serotonin levels in our brain & so destress us.
Just realize that these things will take abit of time to work it's not like taking a pain killer & getting instant results.
Good luck
