Environmental → Some people who have anxiety disorders have it caused by their experiences in life, every place they've been, and everything that has been taught to them; these are the environmental factors.  It's also often accepted that people can develop anxiety disorders just as a result of their surroundings. This is confirmed by the fact that anxiety can be addressed without the need of medication or surgery, implying that life experiences shape a great deal of mental health. Some of these environmental effects are stress, one's upbringing, and trauma. 

Highly anxious people are more inclined to avoid socializing like talking to strangers because it puts them under a lot of stress. They may try to avoid these situations in fear of being ridiculed or judged by others. 

→ Encourage them to reach out to a professional in order for them to take the steps they need to get better and find healthy ways to cope with anxiety. 

→ Celebrate the small steps forward they've taken in their recovery while working to overcome their anxiety, and urge them to keep going.
