I'm being underconfident pls help

I was grinding leetcode but since my placement season took off, all I'm encountering is rejection. In coding rounds people who have never done one lc question is using print statements for visible test cases and getting shortlisted whereas I'm not 🥲. Now I don't feel like doing anything. How to cope up as I'm losing confidence. It feels like my hardwork for the past few months are going down the drain and I'll slip into depression.
