Well-meaning people

My grandma has been, for lack of a better phrase, up my ass my whole pregnancy. I sent her a damn bump picture and she tells me to refill my medications and I'm "worrying her". I'm honestly fine and so is my baby. Just because I'm diabetic she has told me: not to get pregnant ever, not to breastfeed or even attempt, I'm "too weak" to give birth naturally,  and that she'll end up raising my baby. There's literally no basis for any of this and it's really started to make me mad. I don't need to refill my metformin, I Just did a week ago,  I can buy prenatals at Walmart, I don't need a prescription. I can do all the things she's told me not to, because I am a healthy (and responsible) adult and I am sick to death of being treated like this.
