I need some unhinged ways to stop picking ASAP

So i have been picking my skin my entire life as im sure most of you have. I am now 36 and I just started nursing school this past week. I have also been working as a chef the past 13 years. So getting my nails done unfortunately isnt an option since its not allowed in school or the kitchen.

My concern is, I have my first clinical lab this week and we're getting tested on handwashing and hand hygiene. I really want my fingers to not look disgusting and ripped open. I feel like its totally a bad look for them to be staring at me cleaning my fingers and nails while theyre all bitten and unkempt.

So anyways I'm trying to see if anyone has an totally unhinged ways they would get them self to stop picking even just for a few days. My one finger is really bad so ill probably wear a bandaid over that one the next few days but otherwise I dont know what to do. Please help 😭😭😭😭
