Do i deserve to live?

So my parents like my older brother and i dont really mind that its just that they told me they dont have favorites and when my brother does something bad they just let it slide but i do a tiny mistake they sudenly guilt trip me and threaten me and the worst part is they told me i was a mistake and that iwasnt suppose to be born, i know people have worser problems than mine and im sorry about this i really am so please dont be mad at me
