Hi everyone

Hi everyone, I used to be a very confident person who didn’t care about judgment. Lately, I’ve lost that confidence and constantly feel like I’m doing something wrong or embarrassing, even when my actions are normal.
This started after interacting with two people online. One of them opened up about being non-religious. I am a faithful Muslim, and although I entirely reject his views, I chose to respond respectfully and politely without attacking him.
We no longer talk, but I’m now plagued by anxiety and fear of judgment. I keep overthinking: "What if my family saw those chats?" Rationally, my faith hasn't changed and I did nothing wrong, but I can't shake off the guilt.
I don’t want to block them; I prefer keeping them on my list while setting very strict, formal boundaries if they ever text. My issue is: how do I stop this inner turmoil and fear of judgment? How can I rebuild my self-confidence and get my old peace back? Thank you
