Is there a way to see a therapist for free or low money?

Your school counselor is your best bet. Since you are under age, your guardian will need to make you an appointment with a therapist. Here are a couple places in your area, it wouldn't hurt to call them yourself and ask if they charge on a sliding scale (depending on the household income).

Child & Family Guidance Center

Valley Child Guidance Clinic

1669 West Ave J Ste 202

Lancaster, CA 93534

Phone: (661) 265-8627

Hathaway-Sycamores Child & Family Svcs

Community Svcs

44738 Sierra Hwy

Lancaster, CA 93534-3225

Phone: (661) 942-5749

LAC DMH Antelope Valley MHC

349 A East Ave K-6

Lancaster, CA 93535-4508

Phone: (661) 723-4260

The last one is probably most likely a sliding scale clinic as it is state funded.

Your school should have a psychologist or guidance counselor on staff who could refer you to a therapist.

You could talk to your school counselor or you could try your county mental health office.
