My sister keeps picking on me. For context, she's my younger sister by three years. I am neurodivergent, and when I was young I had gone through a lot of strain mentally. I was convinced I was better off dead, my anxiety and suicidal ideation made my secondary school/high school experience a living hell. Only in the last two years have I improved. I am 20, I want to learn how to drive, I am in my second year of college. My sister, 17, refuses to go to a school that she's paid to go to, doesn't do any chores in the house, refuses to do shopping for herself, and still has the never to bully me. I come home after buying her dinner (she asked for the expensive stuff), then she had to call me slow. Not because i took long- but because I don't have "a sense of urgency". I got angry. I quickly stood up for myself, I said that I was depressed and have been fighting to get better. Then she said depression doesn't exist. I cussed her out, she left. I want to believe I am good. But idk.
