If I don’t ask for reassurance or say “maybe, maybe not” it just feels like I’m accepting the possibility :(

What did I do if I really want reassurance

If I stop seeking reassurance will the thoughts become less?

I keep asking for reassurance( which I know I should not do) and when I get the reassurance I want I don’t believe them and I keep asking again and again and again Basically I thought I did something today and my sister was there and I asked her and she said no but I keep asking her because I keep thinking I did this thing. She said she was right there and she saw and nothing happened but I seem to think that maybe she missed something and blah blah blah. My anxiety is even worse now about this topic
