Confused

I am at a point right now where I don't know what to do. My old position at the store has opened up and I am not sure if I want to go back now. I thought I did, I prayed for it to happen and now that it has, why aren't I jumping at the chance to go back? Because nothing has changed since I left. I still have 3 small children who tend to get sick during the winter months and no one to watch them when they do. Which means I would have to stay home and find a replacement for me for that day and possibly a replacement for that night if the one who was covering for me was supposed to work the night shift. Then I would have to find a way to make up the hours I missed which is no big deal if it only happens once in awhile. I guess I could go through the pros and cons, but it still doesn't help. Because to be honest, the cons outway the pros by a ton. Okay, I would love to get back to work. I liked the job and was good at it. I'd be able to get out of the house again and feel like I'm being useful. The money really isn't there, especially during the summer with daycare, but like everyone says, it's more than I'm making now. Now the bad side: I'd be working 6 days a week, my legs and feet would hurt all the time, I'd be tired, I'd hardly see my family, I'd never be able to visit home again, never be able to go home for Christmas, and then back to the I'd hardly see my family again. These past 4 months, Jacob and I have been having so much fun together, but there's days he drives me absolutely crazy and I feel like screaming. I just wish someone could tell me that everything will work out, and magically solve all my problems. These are the time when I start to get really depressed and don't want to get out of bed, don't want to clean the house, don't want to talk to anyone and feel like the worst mother in the world. If I had family living here, like everyone else does, it would be so much easier. I wouldn't have to worry about anything. I love my boys and I love to work. I feel guilty when I work because I'm not spending time with my boys. I feel guilty when I don't work because I'm not "contributing" to the household. And if I didn't have kids, I wouldn't have this problem at all. I need a shrink.......
