Where they differed most
Your friend ends every message with 'sorry for being such a burden' — including one just now, after asking you to feed her cat while she is away at a funeral. Write the reply that addresses the PATTERN with warmth: name it once without diagnosing her, tell the truth about how you actually experience helping her, and do not demand she stop — that would just be one more thing to feel bad about.
Hey—I’ve noticed you’ve been ending every message lately, including just now, with “sorry for being such a burden.” I just want you to know the truth from my side: feeding your cat while you’re at a funeral doesn’t feel like a burden to me. It feels like the smallest, most obvious way to show up for you. Honestly, I’m glad you asked instead of trying to handle everything alone. I’m not going to tell you to stop saying it—I just want my version of the truth in the room too: you’re not heavy to me.
Of course I’ll feed her cat — I’m glad you asked. And I want to say one thing gently: I’ve noticed you often end messages by apologizing for being a burden. You’re not a burden to me. Helping you with something like this feels like being your friend, not like an obligation you need to apologize for. You’ve got enough going on right now; you don’t need to carry that extra weight with me.
