I do not practice in WI, so you would be best to consult with a WI licensed attorney; however, depending on the state, a psychologist may or may not be considered a "professional" in the eye of the law, in order to bring a "malpractice" claim against him/her. Some states also have regulations and ethical standards governing certain professions, which could help establish a "standard of care." Most professionals and quasi-professionals subscribe to professional organizations within their field, which may also have a set of practicing and ethical standards. However, statements of opinion are generally not actionable. Deliberately false statements of fact, which are harmful, may be in certain circumstances. Most of what you have set forth above sounds like simple opinion statements, and unless you have some evidence of demonstrable bias and deliberate falsehood, you probably do not have a legal claim. However, you may consider availing yourself of the psych's professional boards/associations, with the understanding that you may be opening up your records with the pscyh to inspection and review by such boards/associations. Although, such "records" may be too sparse for any kind of meaningful review anyway.
You can sue a ham sandwich. Here, the psychologist is expressing her opinion, thus, don't see a good remedy in a lawsuit.
