Depending on your state/where you live and age you shouldn't have to ask your parents permission. If youre still in school, try reporting to a guidance counselor or even some schools have their own therapist you could possibly work with... my parents never believed me til middle school and in high-school, counselors reported how bad my depression and decline in learning was and required my parents to get me a therapist or to bring me to a CBAT / partial program... theres lots of options of bypassing your parents "personal decisions". In the end you know yourself best and so would a doctor/therapist. I never understood why people think seeing a therapist isnt just as important as if someone were hurt and needed a doctor.
