Did you ask for a raise? Because if not, then this is completely normal. You have two options (leaving out the "just continue and feel miserable"):

- ask for a raise

- change the company

Whatever you do, make sure to have a realistic idea of what your work is worth. Ask fellow employees how much they make and check local statistics about salary in your specific field.
