I have kept my sexuality a secret to my conservative parents. It's time to be free.

I have known I am gay since i was 10, 8 years ago i know my dad will not handle the news well my mother is conservative but i'm sure she'll love me despite everything.How should I come out to them? I want to be respectful and choose my words in a way so they don't get too shocked.Thank you in advance for all the advice
