Hi. I think situations like these where parents treat their children differently doesn't mean that they love you any less. I know that this feels unfair to you but many times, some parents may treat you differently than your siblings depending on the circumstances. They may have trusted you more when you were that age, perhaps they thought you were more mature. Or they may regret letting you take the bus when you didn't want to and the fact that you were bullied and they're trying to prevent that same mistake by not letting it happen to your sister. I can't speak for your parents, but you need to analyze the circumstances before concluding that you're worth less than your sister; no one is worth less than anyone, we're all equal no matter how anyone treats you. This isn't your fault and you are not a failure, I'm sure your parents love you as much as they love your brother and sister.
