hi CT4, please don't let the lawyer's advice paralyse you. Step one, no matter what happens, is to get a job. It doesn't matter what it is or whether it's full-time; it will get you out of the house and give you some independence and something to put on a resume. Many wise employers know that women like you are a great asset for reliability and common-sense. Another way to go is to find a technical area that doesn't require a degree that you can study for. Put some effort into looking around at what's available.
There are very few divorces that don't involve selling the home, and people can become far too attached to real estate. They will often cite the children as the reason why they can't move, but children are very flexible in that area. Please don't ever let your DD over-influence financial decisions - she won't be the one paying the bills.
I suggest you put together a fund for leaving, secretly of course. You can save from the house-keeping, your personal expenses and by selling anything you don't need. This will give you much more freedom of action.
I know it's a bit of a mountain to climb, but at least you can prepare yourself.
