People can spend years, sometimes whole lifetimes, living with anxiety without seeking help. Sometimes this will be felt in particular physical symptoms, for example stomach and bowel problems, or sleep problems. It can take various forms and it can severely limit our capacity to live well. It can make it very difficult to enjoy relationships. Often these kind of anxiety problems have long histories, but the sufferer may never have found a way to speak about them. The anxiety grips in a way that makes speaking about it too difficult.
However, it may be possible to get help. It may be that speaking about these anxious feelings is the beginning of getting to know more about them. This can be the beginning of finding a way to take some control back.
