Dear Abby >> My father died by suicide three years ago. My sister, who was initially supportive, later drunk-dialed our mother and said a bunch of nasty things about her and me. Mom didn’t cut the conversation short and later told me what was said, which included that Dad had done it because my other sister and I are “unstable” and because he was sick.

I haven’t talked to my alcoholic sister for a few years now. She previously ruined a family holiday with a different drunken outburst. She also squandered some money I had given her for a car. I want to confront her, but I know she’ll deny, deflect it back and try to insult me. I have no time for this.

I am disabled with severe recurrent depression and anxiety. I was the one who found Dad after the suicide, and it deeply affected me. I’m floored that not only would my sister not understand this, but that she’d continue backbiting me.

Should I reach out and tell her why I haven’t answered her texts from right after it happened? (She doesn’t talk on the phone, only texts.)

Dear Son/brother >> Please accept my deepest sympathy for the tragic loss of your father. I can’t imagine the degree of shock and trauma finding him must have caused you. By now, you must realize that your sister is not a well woman. Whoever has been telling you about the nasty things she has been saying about you should be told you no longer want to hear it. This includes your mother. As for confronting your sister, I recommend against it. She isn’t going to change. If you haven’t been receiving help for your own issues, it’s time to reach out for some. You are entitled to it. And, for your own sake, continue to avoid your sister and her toxicity.
