But generally, they come under 3 categories:
GAD (self generated):
There are two main criteria for generalised anxiety disorder: firstly, excessive anxiety and worry needs to be happening most days for at least 6 months. The anxiety and worry are associated with three (or more) of the following six symptoms: restlessness/ feeling keyed up or on edge; being easily fatigued; difficulty concentrating or mind going blank; irritability; muscle tension and sleep disturbance.
Specific phobias (externally triggered anxieties):
There are two main criteria for this type of anxiety: fear or anxiety about a specific object or situation (e.g. flying; heights; spiders); additionally, the phobic object or situation always provokes immediate fear or anxiety.
Panic Disorders (internally-triggered anxieties):
Panic disorder involves recurrent unexpected panic attacks – an abrupt surge of intense fear or intense discomfort, that reaches a peak within minutes, some symptoms include:
- Sweating, trembling or shaking
- Chest pain
- Feeling dizzy, unsteady, light-headed, or faint
- Fear of dying
Anxiety – a mental state characterised by worry, concern or nervousness, usually regarding an upcoming task, or uncertain event.
Palpitations – rapid, irregular heartbeat, often caused by agitation, stress or anxiety, or because of too much caffeine, nicotine, or alcohol
