Even though I know that I didn't say something that offends someone...I always check my past conversations in my mind that whether I told something that offends someone or not!😭😢

This is relatable and common! You can handle it, even though it's stressful and discouraging. You can handle the feelings of anxiety and not knowing whether you offended someone. It can help to just tell yourself "yep, I probably offended someone" because agreeing with the ocd stops it from getting more fuel!
