How do i tell my parents about my problems and that I'm gay and trans/nb?

I want to ask my parents for help about my problems but I'm really scared to do this, plus I want to tell them that I'm "gay"(I like guys) and I'm trans/nb (I'm amab)

I'm pretty scared about the part about my issues and being trans/nb (they're cool with being gay etc, but I'm not sure about being trans...), I'm suffering a lot so I think it's going to be too much for them, should I tell them? I can't hide it anymore (dysphoria is terrible)
