Please let the mental health administrator know that you would like an advocate with you. i don't know your age but it sounds like you feel others have authority over you. You can call your state's mental health ombudsman if there is one and/or call a central agency like social services or the local sexual assault clinic. You shouldn't have to go through any of this alone. It's possible those in administrative or authoritative positions just need to document what you're saying but no one should be approaching you as a liar or questioning you like you're in trouble. Some of those feelings could be "old tapes" playing too. i hope you'll get the help you need.
