words coming back to haunt me (I'm worried)

Last night I told my mom I had a blog and she said she hoped I wasn't writing anything about her and dad that is going to make people wonder what kind of parents I have. Oh shit, I can't be alive for this! My mom will come to me with tears in her eyes asking why and it's something I'll never forget! What do I do now? What can I do? What can I say? I can't tell her yeah, I wrote stuff about you and dad! She'll freak! I know exactly how she'll get. Her heart and soul will be burdened and broken by how I could've written the mean things I did! But still, I was just expressing myself, other kids would feel the same as I did and for that reason none of my shit shall be deleted. After I die I want my words to live on (yeah, right) to whoever wants to read them (nobody). God, whatever, please tell my parents I was just expressing myself the best way I knew how, by writing, and I always wanted to be an author, so I just put two and two together and came up with my blog, my career. Is that considered serving you? I'm using my gift to express myself? I'm the democrat who can't be stopped? This is not going anywhere. Oh God, I'll be hurting my parents! But I love them! It's just when they made me angry I couldn't talk back, so I dissed them in my words online. That was my outlet. How many other kids do the same thing? Am I alone? Probably am. No, but seriously, damn, what can I say here that would make it easier for them that I'd never be able to say to their face because I'm ashamed and don't want them to find out until I'm gone what I've done? God, you'll take care of this for me, won't you? Look, I was only doing what you asked! The hate just came naturally. God, take care of this. Don't let my parents find out while I'm alive what I've done.
