I don't care about my relatives
What makes you not care about family?
My family has always acted mean towards be, besides my sister.
If your family is not respecting you, it is fine to cut them out of your life. Those close to you should be uplifting you and helping you out, not making your life worse.
How dare you speak like that to me, I know my family loves me and you don't.
Sorry, I was just operating based on what you said. If you question whether they care about you, you can always speak with them about it.
