One suggestion that hasn't come up...contact your lawyer and inform him/her of this situation. It puts it on the record and he/she can best advise you. I doubt AH or ABIL have the cajones to actually follow through on their threats. Right now they are both acting like 14 year old children (apologies to all healthy 14 yr old.) and are "getting off" on harassing you. Document, document, document...and just let them try to get you in trouble. You will have the evidence and they'll have noting but a lot of hot air that smell like a brewery on overdrive.
I can see how this effected you the way it did...PTSD...but you don't have to handle it like you did when you had no power in the past. This moment, you my dear, do have the power!
