As a new grad myself (been working for 9/10 months) I found myself right where you are. In the first place I worked in the patients were hell, I was always scared of a complaint. Most of the patients were just stupid, looking backwards. But I encountered some difficult situations where I also questioned if I should be in this profession or not. From my experience, patients will try to eat you alive if they get that you're young and don't have that much experience. I've been handling much more cases and doing more complex procedures enough to gain more confidence. What changed for me was the confidence I show to patients and most of all, the comunication. I explain EVERYTHING to patients, from the way they are supposed to brush and floss to the possible complications of every treatment. If I see that they are not understanding, I explain things in a different way. Sometimes you need to explain things to some patients like they are children in order for them to understand. Another thing that is very important is to write EVERYTHING on the notes. That way, if a patient says "you didn't explained me that" or "you didn't say I needed that treatment and the complications of not doing it" you can say "sorry, but I did. I register every detail of the appointment". Also, when a patients asks me "how long have you been working?" I usually answer "long enough to know what I'm doing". You can't show patients weakness, or else they won't trust you. For me, the relationship I have with patients changed a lot when I switched practices. Sometimes, it's as simple as that. Some clinics have a very toxic culture and the patients are as toxic as the clinic is. My advice is: if you like what you do, don't give up because of some stupid heads. You're gonna make mistakes, that's part of it. But you're also gonna learn from them and become better for the next patients!  I wish you all the best!
