Some people find it so difficult to deal with stress that they become extremely anxious. They may have panic attacks, develop phobias (intense, specific fears), experience physical symptoms that do not have a physical cause (such as a rapid heart rate, dry mouth or an upset stomach), or feel a nervousness that interferes with their day-to-day activities. To avoid feeling anxious, some people drink alcohol or do drugs.

Stress can have a big impact on the immune system and increase a person’s susceptibility to illness, so it’s important to deal with anxiety and what lies behind it.
