Take a deep breath, you’ll be fine. Focus on your health first, because you do NOT want to start simlabs with existing bodily injuries. While there are plenty of incoming dental students who’ve had experiences as dental assistants or front desk staff, there’s also plenty of others who’ve worked in completely different fields that are not related to dentistry (or even the healthcare field - I myself was in an office-type job for my gap year since dental offices near me didn’t have any openings). Let go of what you can’t control and keep working hard to recover and save money.
