I have a question about the anti-depressint abilify?

now i posted a question awhile ago about a problem i am having with my body making to much insulin (acanthosis nigricans) and i have this skin problem for a while. i took abilify for a few years and this problem with my skin was present while i was taking it but it was very very little!! i have only been off it for a while most of my pregnancy and since i had my daughter(9mths) and it has gotten ALOT worse since i started taking the abilify 3 years ago. i know that abilify can cause high blood sugar so i was wondering if maybe by taking the abilify it sped up the process of the acanthosis nigricans or if these two things could even be conected (the high blood sugar and the acanthosis nigricans)
