How do you get over hurt feelings when clients and customers complain or verbally attack you?

I edit articles submitted by people who are not professional writers – which means I usually have to do a lot of editing to make their pieces “work.”

In the past few months I’ve had several writers complain that they hate the way I edit, I’m editing their voice out, or telling me that I don’t know what I’m doing – BUT, my co-workers, and even my boss (who did my job for over 30 years) have told me I’m fine. In fact, I was recently promoted to full-time because I was “doing such a great job.”

I know that I’m doing my job well, but still, some of these people I work with can be so defensive and down right rude. I’m really worried that if this keeps happening, my confidence is going to be so low that I might end of leaving this job… But I know that there will always be customers or clients like this at any job. :(

What are your suggestions or thoughts on this?
