Writers block

I love writing. Sometimes i get embarrassed telling friends or teachers I'd like to be an author when I'm older, you may be thinking
'this girls crazy! writings AMAZING!'
or
'pfft writings boring'
whatever, it's embarrassing because, well frankly i don't know. it's like going onto a stage, about to sing, you get embarrassed. Writing is something a lot of people like to do, Cathy Cassi (love her) But she didn't get embarrassed I'm sure. i try not to write anything with meaning at school, teacher's read it and tell you how good it was in front of the class. talk about teachers pet, i know how it feels. feels just the same as like when teachers say my drawings are brilliant! yeah embarrassing but i can't help it! sometimes it feels like i can't write anything good, that what it feels like. like people will mock me, boo me, make fun of me if i try. i guess that's the reason i feel embarrassed. maybe?
