you should be able to get a referral to a counselor from your high school counselor or go see a dr. Where I live they have special services for young people who need help and they are usually free. You could search on google for youth help or youth counseling ... then write your area/city. See what comes up, or you could call a counseling line in your city and ask for free service or confidential service.

if you have insurance on your parents you might be able to get a psychologist or other type of therapist that your parents may help you pay for.

you don't need there permission they probably just feel bad when you have problems and try to blame themselves,
