I've had a similar experience, and I understand your frustration- it sucks to be accused of something you didn't do and have been working so hard to fight! The only advice I can offer you is to give it time and stay strong; someday they will believe you, right now they are just scared. Don't let this get you down-you've come so far, and the only way to earn their trust is to continue to keep yourself safe and prove to them that you have moved on and found better ways of coping. Good luck, and keep up the good work!
