Frustrated

I'm looking for some encouragement because I'm tired of being put down for being a stay-at-home mom who doesn't "work" (regardless of the fact that I take care of our home and children and working on a home business...but no of course I don't "work") and for the size of our family. We are talking about going to get a 15 passenger van. We've found a couple we are going to go look at tonight that might be what we are looking for but apparently we don't know what we are doing because a lot of family members say well you can still fit in a mini-van, one of those 8 seaters. What they don't think about is when we have to put something other than people in said mini-van. Plus, here's where they get even more mad, we might still have more kids! What would we do then, go out and buy yet another vehicle? That's just silly. We need to get into the right size vehicle now so we can start paying it off now. Then years down the road we can just own it outright. What a novel concept wanting to own something without debt attached to it. Grrr... I'm just so frustrated. I know our life is much different than the average Americans but it's MY life not theirs. What they don't see is what is beneath the surface. Like when I'm asked when my youngest will be put into preschool in the fall. I simply told that family member, again, that I will be homeschooling her. She is already so smart and she loves to learn, I don't want that to go away. We have four older children who we have to allow the state to educate (due to our family dynamics it's not something we can do anything about). I won't allow the next one to be state educated too. Our children our blessed to have a father who loves them so much that he is willing to do all he can to give them their mother/stepmother at home with them all the time. These children don't know what it is to have to be separated from their family all the time. Plus the cost alone would make it not feasible for me to work, my income would go negative due to the daycare costs. Alright I'll stop with my rant. If anyone has any suggestions on how to handle family members who just don't understand please offer some suggestions.
