You should have your son evaluated by another neutral medical/psychological professional and see if he/she agrees you son is being over medicated or emotionally abused. If so, you need to file an action (or a motion in the cause if there is already an existing court file) asking the court for full or primary custody and ordering your ex-wife to pay a fair share of uninsured medical expenses. (If she is already under order to do this then you should file a motion for contempt.)As far as your creditors go, they don't care about your custody/support situation. If you are the guarantor, you are ultimately responsible.
