how to tell my parents about my struggles

tw: mentions of self harm

I don't talk with my parents about mental health at all, but I've recently been dealing with a lot and I've noticed that I have some symptoms of depression. I've also been cutting on and off for the last few months. I want to tell my parents that I want to seek professional help but it still feels stigmatised in my home. I'm a minor and can't get help on my own, but I'm so afraid of what they're going to say.I don't talk with my parents about mental health at all, but I've recently been dealing with a lot and I've noticed that I have some symptoms of depression.
