The condition known as 'anxiety' is quite hard to define in a medical sense, but it usually manifests itself with excess swearting, shortness of breath, feelings of panic and paranoia, claustrophobia, and a variety of other symptoms. If you do not have any of these, it deosn't mean you don't suffer from anxiety - the fact that you feel concerned enough to post this Question means that you have something on your mind. See your doctor, who will assess your situation, and prescribe or refer you as appropriate. Don't worry about not being "anxious enough" - if you are concerned, then your doctor will accept you with a legitimate condition, and he / she won't think you are pathetic. This condition is far more common than you might think, and your doctor will be able to put your mind at rest.
