R blogs supposed 2b like ur diary

Am I doing this wrong? I used to keep a diary, from elementary school on up. In my adult life I've called it my "Journal" but now I write here. Am I doing this wrong? Am I sharing too much? Do u even wanna hear me whine like I do, because fog has set in? I don't know I read other people's blog and they have a real sense of purpose and structure. Mine is totally moody, and truly about "A day n da life of Lizzy".  I don't know maybe I shut this whole thing down.....
