Before School Year

This is how I am feeling right now:

I am usually the one who goes back and forth. Everyone in the neighborhood says that the quality of school here is excellent and is shocked I wouldn't take my kids there. Maybe... Maybe it is excellent, but I cannot make myself send them off for 7 hours each day doing who knows what. I just can't. But I also feel so incompetent to teach them! I have a Finance degree from BYU (never worked though) and have tutored Math to many students of different levels to get my husband through school. But when it comes to teaching my own children full time at home - I panic! I see all these other posts of different curriculum other parents use and my hair stand up on my head. I cried - literally! I can't afford all of it! I can't even choose which one! I can't find the time to teach it all to them!? Do I know science well enough to teach it? What science should be taught to a 1st grader? There is Biology, Chemistry, Physics. To 1st grader? What?! People teach Latin? Did I sign up for too many co-ops? Would I isolate my children too much if I cancel half of them? WHAT DO I DO??? See - panic! My husband is the one who tells me it's the best for the kids. They waste a lot of time at school (and he was a middle school teacher for a while at a charter school). HE wants me to homeschool. He says just do the basics. But how can my children keep up with the world and other students if I just teach them the basics. I am SO overwhelmed! Would they know enough when they DO go to school when highschool years come? Gosh.... But, my husband is right. Even my mom, who wasn't around much when I was growing up, agrees with him. Somehow I need to find a way to calm down and put myself together and just do it. And my kids don't even bicker much, they get along really well. Kinder and 1st grader.
