Forged my own lost documents, what's the worst that can happen with me ?

Nomoskar raiz, I had applied for a government aided course and there'll be document verification and interview for the same on Wednesday. Unfortunately I had lost my caste certificate (original laminated copy) while shifting (I am obc). The original document was made when I was a kid. I had photograph of the original document and used it for Xerox purposes or online submissions. But now I've been asked to bring along all my original documents on Wednesday. Problem is that there are only 15 seats and 25 candidates. Upon asking an employee I got to know they might do selection on caste basis hence I don't wanna lose this opportunity because of a lost documents. Applying for new obc certificate would first need applying for income and will take around 15 days minimum and I need the document on Wednesday so I got my obc certificate photograph Photoshoped by a professional and laminated it...but still upon a few close glances one can tell it's forged . What are the chances I might be caught. Also will there be severe punishments? Should I use the forged document or not ? 😭 I'm so nervous and anxious at the moment. please help me out.
