I hope you have gotten out of the abusive situation and have someone responsible handling your affairs now? No, they can't have your pay garnished, but, presumably (if they win and I wouldn't say it looks good for them, withholding your meds and trying other tricks like writing checks on your account) they could get any bank accounts (where you have money, but since you don't have any money. . .)
