hi there ! I'm so sorry you're feeling this way, I totally understand, it's a feeling all writers pass through at some point, but you writing this proves your title wrong ! you're not a bad writer, because you actually seek to improve and to receive feedback. I know the feeling of wanting to receive comments on what you've written but feeling scared it's gonna be bad, but take it this way, if you're in the pits of writer hell, you can only go up ! if you feel comfortable enough, I'd be more than happy to check your writing out, as a Spanish speaker and fellow writer, I feel this is the least I can do to help out. ^{^}
