K.P.
I'm sorry, but I'm not seeing your actual question here.
Having said that, you should seek legal counsel. It doesn't sound like you have an attorney, but your ex does. If you do have an attorney, get a new one.
I cannot imagine the pain of not seeing your child, especially if you feel that you are being wrongly accused. As a psychologist, I can tell you that the MMPI is an older assessment of personality, but don't blame the test! The results of that assessment do NOT indicate a diagnosis and that is not the purpose of the survey. The MMPI is used to characterize your personality type, not indicate Borderline Personality Disorder. It is very common for marriage counselors to use a similar instrument to help identify why people are unable to communicate.
You say that your are mandated to take medication and go to therapy. Did the independent psychiatrist recommend that as part of his/her assessment? If you have undergone a comprehensive psychiatric assessment by a court-mandated doctor then his/her findings would be binding in court. If that individual feels that you are an unfit parent, you would need to have an independent evaluation conducted to refute that information. Your attorney can subpoena your therapists, but be aware that they may feel the same way depending on their impressions of you.
Who made the CPS calls? That worries me b/c others are concerned about your parenting ability, including the school principal. Is it possible that your anxiety is more than you are aware of yourself? The length of this post and immediacy of it would indicate concern from a clinical standpoint.
I am concerned that you sound like you are reeling and are currently on a medication. Schedule an appointment with your attorney and ask about an updated psychiatric assessment- for you and your ex. I have testified in custody hearings regarding the impact on the child, so your daughter should be evaluated as well.
Unfortunately, it is very difficult to reverse custody pendency when there is a mental health concern involved. A good attorney and a new battery of assessments (for ALL involved) is warranted. It is going to cost you a lot of money, but you may be able to see your daughter more often!
