Okay so to give a little background, I got a 2% raise (a whopping $.20!) a few months ago. The place I'm working at didn't have a 3 month, 6 month and 1 year evaluation like I've experienced in the past. Instead I just had a 1 year eval which is when I got the raise. However, I have gained way more responsibility since my eval/raise and feel that I should be compensated for taking on extra work that is not in my original job description. Here's the problem though...my boss is the most intimidating person I've ever met and every time I build up the courage to go talk to her, she will randomly bring up an old mistake I made or have something negative to say so I get discouraged all over again.

Anyway, any advice would be helpful on how to approach this situation.
