Oh honey, I am so sorry your family is treating you like this. This is small consolation from an internet stranger, but if you you don't have another place to go (moving in with a friend? Aunt? Grandparents?), and you have no choice but to stay at this residence (this isn't a home!), please keep in mind that your situation will not last forever: as soon as you can free yourself from your toxic family, do so, without guilt. They deserve no contact from you. You can fly without their weights pinning down your wings.

When I was little, I was friends with two twin girls - one was the "pretty, popular one" and the other was always an afterthought. I'm ashamed to say I was too young and dumb to notice it at the time, but my mom did, and was always furious at how disparate the girls were treated by their own parents.

You family has spent years showing you who they really are. All you can do now is believe them. I'm sorry. Hugs to you.
