Sounds to me like this friend has gone through similar experiences and this is their coping mechanism.

Compromising your health as a ‘means to teach’ is not good parenting. Physical abuse and starvation are recognized means of torture, as far as I’m aware. Please seek help,if possible.

As for your friend, if you’ve already tried explaining your situation and that still doesn’t register as abuse, you can tell her that you require support at this time, not additional work from someone in a position to support. It’s ok to take a break from her for a time while you try to better your situation.

Best wishes bud, hang in there.
