It can really help to have someone you're out to who knows both you and your folks to have your back in case anything goes bad

Now this can admittedly be very difficult to do, but do everything you can to remain composed, to give the impression you know what you're talking about

So that your parents don't think you're just "being trans on a whim" because yes, that is something that can happen :/

Try to emphasize how you've thought this through, talked to lots of people about it, sound certain in your declaration.

That's all I have at the moment.

*hugs* I hope everything works out for you Celica.
