My father in law just learned that I used to self harm

I have a decently large wrist tattoo that covers self harm scars (which is the only reason I got the tattoo). Him and I were discussing tattoos and tattoo removal when I said I wanted the one on my wrist removed, he asked why, and I nonchalantly said “I only got it to cover up some pretttttyy bad decisions” and then immediately realized what I had just told him and regretted it. He said “oh” and looked very worried, and we just kind of fell silent while he looked at me as if to say “are you okay” and “I didn’t need to know that” at the same time. The rest of the night was pretty awkward while I tried to fake happy and go back to normal because I had let my guard down accidentally and I couldn’t stop thinking about how he must be looking at me differently. I don’t want pity. I just got home and I feel this deep pit in my chest like I just screwed everything up
