I (30F) have an older sister, L (45F), who has struggled to hold down a job for the last couple of years. She’s been living with my parents after a breakup, and for the past 4 months, she’s been sleeping on their couch. She has mentioned that her mental health is a reason for not looking for a job, and while I’ve been supportive of her, I also deal with mental health challenges myself, but I continue to work and contribute to helping our parents when I can.

Last night, we were all at my parents’ house when my sister tried to confront my dad about something he had said. Instead of just bringing it up once, she kept repeating it, and it became hard for anyone else to speak. I want to clarify, I’m not trying to diminish anyone’s struggles with mental health, but I was trying to have a different conversation, and the situation was triggering my anxiety.

Eventually, I decided to leave the room because the tension was too much for me. Shortly after, I overheard them arguing, and my dad told her to leave his house and not come back. While I thought his response was harsh, I understand where it’s coming from. She hasn’t contributed to household bills or helped with any of the cleaning, and my parents are trying to retire soon. They can’t do it alone financially, so thankfully, I work full-time and chip in when I can.

Since she left last night, my sister has been blowing up my phone with hurtful messages about my dad, and I just reached a breaking point. I had to block her because I’ve had enough of the drama. AITAH?
