oh dear. that's a bad situation.
best to consult a lawyer quickly, westbank.
if it was me, i wouldn't put my limited energy into pursuing the human rights/slander suit. that will use up more of your resources. i'd let that one go, however unjust, and put my energies towards getting a new p/t job and dealing with the house/mortgage situation.
realistically, there is only so much you can do and you'll have to choose your battles wisely or exhaust yourself trying to do it all.
jmho. feel for you.
