I am sorry to hear about the unfortunate situation you were in because of Depakote related liver problems.
Depakote is licensed to be used as a mood stabiliser ( mostly for patients suffering with mood disorders
such as Bipolar affective diosrder). However a lot of practitioners do use this medicine in other disorders where there are mood swings or alterations. One such disorder is Borderline Personality disorder
Your first doctor was not wrong in prescribing this medicine as there are ample of research evidence to support it's use BUT he was wrong in not discussing about this with you beforehand - esp. because some insurance companies or medicare may not agree to pay for the prescription for off-license use - thus putting you at a risk of financial hardship.
The elevated liver enzymes
is a known side- effect of Depakote as it is metabolised by liver. Most prescribers do (& should) warn the patient about it and also do regular tests to look for same. They should also warn the patient against use of alcohol & other hepato-toxic medications - which again can put stress
on pt's liver. If your doctor continued to prescribe and increase the dose of depakote when you were clearly having side effects plus had lab reports to show evidence of raised liver enzymes - he/she was clearly wrong.
I must say that case however against the doctor ( if you plan to sue him/her) will be weak unless until you can show that there was evidence of raised liver enzymes but the prescription of depakote was kept same or dose increased.
With regard to Borderline personality disorder - I will recommend that you engage with a psychotherapist or psychiatrist
with experince in DBT ( Dialectical behaviour therapy
