If you take the stance that anxiety is a rather thin presentation of fear, then the self help is under way. Within our working years, anxiety has a part to play as a spur, a force that drives us to seek perfection,timing,presentation etc. If it comes "out of the blue" for no apparent reason then its role is reversed to that of an anchor holding a person back from achieving, doing. Initially it distracts but can move to domination. At some point you will realise that the "what if" part of the anxiety rarely happens and when that event is passed the tendency is to search for a new "what if". As has been suggested already, look to curtail the caffeine consumption, a food intolerance, over indulgence in alcohol etc. But,...take a rational look at your self. Have you too much time on your hands, do your days feel unfulfilled, have you a goal in life or...do you cater solely to others! Exercise as often as you can...outdoors...not in. Take up doing something of interest which can not be completed in a short span of time. Allow yourself time to be you. Talk about your feelings with others...you are not alone. Write down the good things you have been involved in and savour the feelings of that time. My personal panacea was to take up painting in water colours....it worked for me. Wish you well Lowell.
