I do suffer from anxiety, but usually find that I can cope with it. My advice to myself, (which doesn't always work, but I feel is a good starting point) is to face it head on. First decide what exactly is it that you are anxious about, then look at the situation from a purely practical viewpoint. Is there something you can do about this situation? - if so then DO IT. Take whatever steps you can take that might improve the situation. Look at it from every angle. Talk to someone about it. Ask for advice, or if the problem involves someone else, then talk to them. If after all that there is really nothing you can do about it, then put it out of your mind. Be positive, and trust to fate. Often things turn out in a better way than you expect anyway, and if there is nothing you can do about it, then getting anxious is not going to help. Concentrate on something constructive which will then occupy your mind and dispel the anxiety.
