another dog eat dog day

I don't know what to do with my class. I don't want to be all strict with them but I don't want to be lax with them too. I feel like I'm failing as a trainer at this point, even if we're just starting. I want things to go well, for them to understand, to be able to do well when they get on the floor. I feel that I will let the people down. I hope I won't. I'm having all these insecurities, that I'm not a good trainer, that I'm just winging it. I can't help but compare my class to Ivy's, that she's doing so much better than me. And I feel like the onaks like her better too. I don't know what I'm doing wrong!!!!
