Not sure of your financial standing. I would recommend consulting a lawyer though, that may be the best thing you can do right now.
Although you haven't committed a crime, I do agree that if the courts deem you a danger than can and will commit you against your will, and given the current hysteria against our kind...
The recommendation to see a psychologist on your own is a good idea too. Walk in and be frank with them and get their initial reaction. If you can find someone willing to be partial and not biased it will help.
Contact b4uact. They are based on the east coast somewhere (MD?) and are sympathetic to MAA's.
Try Michael Melsheimer as he often posts here and is proactive in MAA studies (and perhaps rights).
Next...calm down. Take a deep breath. Panicking and doing something irrational will only make things worse. You will come out of this one way or another, so try to face it rationally and calmly. Don't think of the worst case scenario, just focus on things you can do to help yourself. But be prepared to give up your job working near kids...if that's the worst that happens, then you should breathe easily.
Finally. If I were in your shoes, I would disown my family. With family like that who needs enemies? And I wouldn't walk away from them quietly.
Also...do you have character witnesses? Friends that will support you, speak up for you in RL? Ask for their help and guidance.
