Is talking to my parents abt this a good idea?

I'm not sure how to talk to my parents that I want to go to a therapist, not a counselor. A therapist. I know my mental health is bad and there's things I do that aren't good, I want to know what causes them, I want to know what is wrong with me, I want to know if I should be actually doing something like take medication or anything to help me, but I don't know how to talk to them. My dad doesn't believe in therapists and just the science part of life and even the mental health and believe taking medication is awful for you and he'd rather use weed as a medication. While my mom's on the science stuff of it and believes in it but she'd rather me use the counselor at her work but I fear if I do that, the counselor will just tell my mom everything bc they're co-workers. That's why I never spoken anything personal to that counselor, I don't see her anymore too. And I don't want to keep hurting my friends and/or partner or family. I can't do that bc then I'll worry and hate myself for hurting them and then it'll just get worse and worse and it'll just spiral out out control.
