Is there any test that can be done at home to confirm gender dysphoria? i'm having it for 10 years. but my parents think it's in my mind.

Best bet: Is to sit down and discuss your concerns with a psychiatrist that specializes in this particular area. They are keenly adept and explaining and helping you understand what might be going on.
