This site gives me anxiety all the time 😅

Neither is true. If they're annoyed, it's their doing. It's not something you've said. And if they don't like you, they just don't have good taste. You're doing just fine. There's no need to be anxious here. This is an anonymous site. No one can see you. Just be yourself and say what you want. Your kindness will be appreciated by people who see it.
