I'm sorry to say that users will always be users. They will never change. They will never learn. They don't want to or need to.
If your customers are coworkers, you should be able to expect a certain level of professionalism from them.
If your customers are external, you're pretty much stuck with however they treat you, unfortunately.
The burn out rate on that job (for me) was at about seven years, n00b to vet, entirely due to lack of respect from customers and lack of support from the person to whom I reported.
I recommend you grow your skills, start thinking about the next level, and be aware that, unless you are able to accept the abuse of your customers, you may not be wired for that job. I certainly am not.
Every job in IT involves a certain level of customer support; in some other IT jobs, however, you may have a more informed and professional-behaving customer base. I've been programming / webbing for a few years and really like it.
Be well. Get lots of sleep. Eat right. Exercise. Floss. Take good care of yourself during this time of stress.
Good luck.
