Diares or Talking to someone

Okay so unpopular opinion, but I dont like diaries :\ To me they are pretty pointless. What's the point of writing how you feel if you already know how you feel yn ? Or am I just stupid (TT^TT) ?? Personally I think talking to someone or posting about how you feel is better because you're actually expressing emotions to a person or group of people who can give you support and guidance on how to feel better. A diary doesn't do that- You are still holding in all those emotions except now its in a book D:< !! Idk maybe you guys can give me some reasons that could give me a better outlook on them-- Another reason I dislike diaries is because of nosey families ! I have a very nosey father + sister and if they were to find even a single page of my day to day feelings I'd probably be in kids peace or something (TToTT) So my conclusion is that I feel as if people should talk to others abt how they feel not paper :\ And I understand people have issues when it comes to talking about feelings but i dont really understand what writing their issues would do for them.
