Nanny Job Gone Wrong: A Frustrating Day

rant - today needs a reboot ever since this late morning. The job for nannying that I got, was supposed to start today, and my GPS went out on the way there. It was for this lady who has a ten-week-premature baby and she wanted to visit him and she needs me to watch her 2 year old while she goes to the NICU to visit the baby boy. But my GPS went out, and I didn't leave the house in enough time for something like that, and she lives in Mapleton. So I tried finding it without my gps, and accidentally found a similar address in a neighboring town, and I thought I was there, and waited at the door, and I called her and she was understandably frustrated. So, she doesn't get to see her boy today because she didn't leave in time to visit him, and she said let's just forget about today. Aside from getting some time away from my son so he can become less dependent on me, I was excited to have a job because then we would finally have some money, because we literally have none (actually -$150 in our bank) in order to get the prints that we needed for Ethan's bridal fair booth, we needed to take all of the bills out of our jar of change and use them. That jar of change was supposed to go toward a cruise and we've been saving for 5 years just to use in one day on Prints for Ethan's business. I obviously want his business to work out, and we haven't gotten any bites yet except for one wedding next summer. And it would be one thing if this job was only like $10 an hour or something like that but it's $25 an hour, so I'm worried that she will just find someone else before monday. I want her to know how good I am as a nanny and so I was wanting to get references, but I just don't know if she'll trust me now anyway. I was so nervous and frazzled after that, at the Smiths I walked around for about an hour and a half and drank a whole energy drink that I found in our car, I don't usually drink a whole can, and spent a while driving around before I came home. In order to fill up with enough gas to get home, I had to use the last $2 of quarters that I found in the car. My in-laws have helped us out so much already, they don't have any money on their debit cards anymore.
