good or bad??

So, I got a job tonight. I saw an ad in the paper for data entry not too far from here. I went and applied and took a typing test and a written test last Friday, and got the job. It is 3 days a week from 6 till midnight. The pay isnt horrible, but its not great. The hours are ok- sort of. I am going to feel horrible that 3 days out of the week, Andy will get home from school and I will have to be rushed out the door to go to work until midnight and then be up early in the morning to start the day again. I feel like a bad mom and like I will be missing out on fun nights at home and making bad memories for the kids when they are older. I am freaked out to leave the building at midnight. I dont know if everyone else works until midnight too, or just a few?? It is an industrial area surrounded by a weedy swampy area. I should be excited to get out of the house for a little while- but I'm not. It is only 3 days out of the 7 days of the week... but I just dont feel it with this place.I am only doing it for the money.  I am hesitatnt and sort of regretting that I said yes tonight. I am seriously trying not to cry thinking about leaving my kids to go to work 3 nights out of the week. I dont think it would be so bad if Andy were still at home and I got to see him all the time like I do with Justin and Ryan, but he is at kindergarten...ALL DAY LONG- EVERYDAY. I am so bummed out. I guess I'll try it and see how it goes... but I feel horrible about leaving  here to go to work. It will be like I say, "Hi Andy,  how was school- ok...bye. See you tomorrow morning."  Too sad. I dont know if I can even do this now that I am typing this and thinking about him. Atleast I get to spend time with the younger ones during the day...but not him. Maybe it wouldnt be so bad if I felt better about the place to begin with?? It seems weird. I just dont know if I can do that to him. I already feel like I dont spend enough time with him. I dont know what to do. We need the extra money, but how do I look him in the face and leave him right when he gets home from a long day of school????
