I gave sincere advice and they walked away worse

I need to say this out loud because it keeps looping in my head. A few weeks ago I sent a long voice note to a cousin who was losing their patience with life. I spoke gently, shared a hadith I love, and recommended a dua that helped me after my father died. They replied with anger, accused me of being self-righteous, and left the family chat. Later someone showed me a screenshot of a message where they made me look like the problem. Now I am terrified to say anything about deen, even a quiet reminder, because what if I make things worse? Has anyone else felt this freeze after trying to help? How did you live with that fear?
