What can happen if i don't get any help for gender identity disorder?

Depression: Failure to get help dealing with your gender identity can result in confusion and depression.

Gender Identity D/O: People with gender identity disorder often suffer greatly. Depending on the support and treatment received, they are at risk for many additional problems such as anxiety, depression, substance abuse, and suicide. Many become socially isolated, not sure of where they "fit" or whether to visibly show their gender identity in public. Treatment is a long road, but can lead to more self-acceptance.
