I reported my debit card lost/stolen. I thought I lost it but then I just found it in my pocket. Can I just reactivate it?

I feel so stupid for this. I really just had a mini heart attack thinking I lost my card. And it just magically appears in my pocket. Now I just had it cancelled for no reason and will have to wait 7-14 business days to use my funds again. Can I just call and say I found the card and use my original card?
