Wait a minute, you can't go to prison without a trial and she has to have actual "proof" for this and more than accusations to actually go to trial. You need to find a lawyer that can explain all of this to you. If you have proof of her admitting she has ptsd then your lawyer can use that against her. It sounds like this woman has more than ptsd, she may also suffer from a personality disorder or possibly even schizophrenia.

In severe cases of ptsd a person can get triggered and experience flashbacks that can confuse them. If she suffered a lot of abuse then you just coming through the door can be a trigger as her abuser may have come through the door many times and behaved towards her in abusive ways.

If all she has is letters, if you were nice and did not say anything threatening in them then that's not evidence that you are a danger.

Given that she needs so many drugs and is even mixing these different drugs can mean the drugs are possibly adding to her challenge.
