What should I do about feeling unappreciated at work?

Definitely, ask for a raise. Also, ask for an honest review of your work. This will give your boss a chance to tell you all the things she likes about what you are doing. If you don't get either of those things or even if you do, continue to look for other employment. The sort of person who never says how they appreciate you is unlikely to change. Rather than waiting for her to be different, be proactive and go find a boss or situation that will appreciate your commitment. There are lots of companies wanting employees who are invested. You are a catch for the employer.
