How can I stop overthinking a parent’s criticism of my homework?

Last night, one of the parents told me that I assign too little homework and that the child isn't taking their tasks seriously. It might not seem like a big deal to others, but I couldn't sleep all night, letting a thousand thoughts spin in my head: Am I not a good enough teacher? Am I not demanding enough? Am I earning my living honestly? Has anyone else experienced something like this? How can you help me cope with these feelings
