idk what to Do no more

lately me and my mom have been arguing a lot but we argue over stupid stuff she always defends my brothers more than me like always if they do something wrong she always blames it on me my brothers literally scream at her face and say bad words to her face and it seems like she likes them more I've never yelled at her and never disrespected her but she always treats me like shit and I'm the one who shows her more love today we argued and she told me that she wishes I would go away far from her that I bother her In her life and that the bad thing is that my dad doesn't want me either so I really don't know what to do sometimes I wish I can go far far away or sometimes kill myself idk what to do what should I do I really need to go somewhere I don't wanna stay here anymore after what she told me 😕😕
