Being mentally strong and self confident is a trait that you can practice irrespective of any disorder. Because you cannot give up to something that is not caused by you. You should be ready to face any worse situation with a smile on your face, cause thats life. For your jaw and muscle disorder, get consultation from an oral surgeon and practice physiotherapeutic exercises. Meditation and yoga can help you calm yourself.

You need to see a psychologist to help you cope with your illness. TMJ disorders need to be diagnosed and evaluated correctly for treatment to be instituted. Best wishes.

Din get ur question right , if u could please explain , what’s d issue

Get your TMJ problems treated to get relief from discomfort as much as possible. Practice yoga, meditation etc as stress always worsens the discomfort. Try to get exercise in fresh air everyday and get enough sleep. This will help you overcome these issues
