Why does generalised anxiety disorder cause feeling anxious?

Feeling Anxious is a very common presentation of Generalised Anxiety Disorder. The feeling may show up as persistent worry, dread, irritability, difficulty relaxing, or a sense that something needs to be dealt with straight away. The body can join in with a faster heartbeat, sweating, trembling, stomach discomfort, or tense muscles. Worry may shift between topics such as health, work, family, or everyday responsibilities. This response is real and distressing, even when you can recognise that the feared outcome is uncertain.

Name the feeling as anxiety, then choose one grounding action: feel both feet on the floor, notice objects around you, or lengthen your exhale without forcing it. Limit repeated checking or reassurance-seeking when you notice it feeding the worry cycle. Set aside a short time to write down concerns and separate actions you can take from matters outside your control. A clinician can discuss structured talking therapies, self-management approaches, and whether medicine may be appropriate for your circumstances.

Make an appointment if worry is hard to control, is affecting sleep, concentration, work, relationships, or physical health, or is leading you to avoid normal activities. Seek urgent mental health support if you have thoughts of harming yourself, feel unable to stay safe, or fear you may harm someone else. New chest pain, fainting, severe breathlessness, or neurological symptoms need urgent medical assessment.

Ask how generalised anxiety disorder is assessed, which treatments may be suitable, and how long it may take to notice change. Explain your worry themes, physical symptoms, sleep, current coping strategies, and any alcohol, caffeine, or medication use.
