I always had a rocky relationship with my mother. In particular, she's always been obsessed with my weight (this caused some significant anorexia/binge eating during my teens that lasted a few years).
I moved far away from her (while still maintaining contact) and it got much easier and our relationship improved significantly.
Due to childcare, she moved close to me and DP and she started commenting again on my weight.
Although I have not had any food problems since moving out, her comments still sting and are hurtful. Moving far away is not an option as we really need childcare. Telling her to mind her own business won't solve it as she will just keep doing it.
What would you advice to maintain my mental health?
