I'm not sure I like the new job

My job is really wearing me down, even after 3 days. I never seem to have time to do everything, I'm constantly running, and I wasn't adequately prepared by the former person. Plus the raise isn't what it should be yet. Maybe after I've been at it a while things will calm down, and I hope when I get word that I passed my classification test I'll get more money. I guess I'll just have to hang on a while.
I really just wanted to keep doing my old job until I retired.
