I read your topic and though it took me a (short)while to decipher it, I got it.

But why post it here on QL?

You should have contacted your previous students and ask their help or even that student you were with that "friday"?

I could say a lot more...but since you're already in a situation, I don't want to add up to your bad feelings.

Good Luck and I hope you will overcome this trial...
