It’s not a joke to me, but I deeply apologize if I made it seem that way. I defended my mom’s actions and I shouldn’t have.

You got me when you said I have higher expectations for my sister than my parents. I didn’t even realize until you pointed it out and you’re absolutely correct and that’s messed up. Honestly, I’m really afraid of causing conflict with my parents because of how it was like before my mom remarried, but my sister shouldn’t be the one to suffer when I’m the pussy. I’ll try talking to my parents tonight about seeing what we can do about therapy for my sister and also confronting their behaviour.

Thank you for your response.
