Is your mom someone that keeps secrets? Do you have a good, strong, healthy relationship with her? If so, I would wait until you're with her without your dad (and in a place she's focused on you, on a day she's not irritated or stressed) and say that a classmate that you recently had befriended (come up with some details so it sounds believable) had come out as (whatever you want to come out as) and you weren't sure how to react. Ask her for advice, and depending on what she says you can decide whether or not to come out. Hope this helps! We support you unconditonally!
