It sounds like you're going to need a lawyer, I don't know how you get out of this without one. At the very least have a consultation with one (they'll usually take an initial meeting with you for no charge), tell him the situation and see what he says.
You should be entitled to half of the marital property. The court won't look at it as "she made $1M and you made $100K". They'll consider that the MARRIAGE made $1.1M and you're each entitled to half of the benefits. So you are entitled to half of your home, half of the value of the cars, half of whatever is in any bank accounts, etc., etc.
In addition, due to the disparity in your incomes and your sacrificing your professional life to support hers, you likely have a case for her to pay you spousal support while you obtain any training you need to become self-supporting. Plus child support if you're able to get some share of custody.
So you're not entirely screwed, but if she has an aggressive lawyer and you try to represent yourself you will be.
