Anyone still feel anxious despite paying off the debt?

I am super proud of myself for killing a $9k credit card bill that I’ve had hanging around for about 3 years. But two weeks later I’m still feeling very anxious about money. Part of this is I just got my first debt free paycheck and a bunch of it still had to go to necessary unfun stuff I put off during the debt payments. But I’m just feeling still really shaky and worried about it all despite being in a way better position now.
