Any advice on taking up a second job?

I’ve been feeling extremely depressed lately after the recent death of my mother and stepfather, and I’ve been wanting to do a few things to make me feel joy and worth living again. I’m willing to take a second job for a few months to accomplish it. Does anyone have any advice for working two jobs? I want to take a much needed vacation with my family. The problem is that I need to get my finances back on track to do so.
