tough sigil
17 year old transfem in really transphobic country. I have a few friends irl who are aware of it and accept me, especially my bestfriend, who is helping me to deal with gender dysphoria A LOT.
Now I'm thinking whether or not should I come out to my parents any soon, and beforehand - I'd love to hear all the details, and I'm extremely curious to hear transgender people coming out stories to their parents, just so I know what to expect; advice and support is extremely useful! <3

if your parents are transphobic I wouldn't recommend coming out to them, especially in your country. it's probably not safe, especially if you're living with them. /lh
if you know they aren't transphobic, that's awesome. if you're comfortable, you can just tell em, hey I'm actually trans and I wanna go by these pronouns or I wanna change something else. it doesn't have to be a big thing if you don't want it to be. I first came out to my parents as non binary, but recently told them I want to go by he/him instead of they/them, so I believe they think I'm trans (which I am). and mine are very accepting, which is great, it's just kind of a casual thing with us it's not really huge or a thing we talk about a lot unless I need to. I really wish you luck on this :] if you're worried about coming out, just know I'm with ya. I understand. but I believe in you!! you got this 
or if you don't really wanna just tell them (or can't) you could try writing it down :3
