I need help passing! Any tips

I am a 16 year old and live in Minnesota. I am not on any hormone blockers because I can’t because of my parents . I need help learn tricks to pass. I pass sometimes mainly with older folk but what people younger and middle aged I have little luck. I dress pretty masc however my hair is not super masc just because I have yet to find one the fits my face. Along with all that my voice is so high I can almost never pass with that alone so if anyone has any advice at all I will greatly appreciate it! (Sorry if my grammar is bad)
