Do you agree telling someone to "just have confidence," is dumb, since confidence is not going to come form thin air?

I can't stand when people say that. When doesn't have confidence is for a reason. For example, I don't have confidence for different types of reasons. One reason is because my whole life, people have said I can't do anything right, I'm stupid, made fun of me, etc. Including my family. Top it off I have been bullied in grade school, college, at work, etc. You can't expect me to just have confidence when so many people have treated me like shit. It is the same with other people with low confidence.
