Short answer--

1. You may very well have a valid cause of action against your employer.

2. Such a suit brings MORE attention to the reasons for your discharge instead of letting it fade into the sunset.

3. You may/may not win and you may/may not get substantial damages.

4. You probably ought to check into a divorce lawyer at the same time.

Sorry, but I'd put this one behind me and try to put the family back together as much as possible.
