Can you join the army if have social anxiety disorder?

The answer is: no

Social anxiety disorder is a mental health condition that makes it difficult to be around other people. People with social anxiety disorder may feel anxious, embarrassed, or self-conscious in social situations, and they may avoid these situations altogether. This can make it difficult to hold a job, go to school, or participate in other activities that involve interacting with other people.

The military is a demanding environment that requires people to work closely together in high-stress situations. People with social anxiety disorder may find it difficult to function in this environment, and they may be more likely to experience problems such as depression, anxiety, and PTSD. For these reasons, people with social anxiety disorder are generally not eligible to join the military.
