Happy that this helps! I totally understand how it’s hard to figure out what you can write about if you’re still young and haven’t experienced many things (and it can be very pressuring if you’re worried about what people may think).
Overall, I would say, always make sure to research and talk to people who have experienced that. Ask for people’s opinions when you are unsure what you can talk or not talk about!
Don’t feel scared to ask because it’s always better to learn now than later. Feel free to come back here later to ask something!
