Husband has been really dismissive about all of this

I’ll admit that I can be anxious and sometimes complain; but overall I think I’m doing a really good job of managing my GD diagnosis and everything that’s come with it (diet changes, monitoring my glucose, now insulin injections at night). I occasionally complain about it or express anxiety about what will happen as the pregnancy progresses (ex. Will I need to be induced, will baby get too big, etc.). All I’m really looking for from my husband is empathy and reassurance. Instead, he often tells me that I’m dramatic, freaking out about nothing (I don’t think I’m freaking out, I just find it helpful to express my thoughts and feelings; I’m calm when I do so). He’ll also often give me unsolicited medical advice like “doctors don’t know what they’re talking about” and “modern medicine is wrong about most things..” We just got into a big fight about this and he got very defensive and essentially said to stop coming to him if I don’t want his honest opinion. I’m hurt and I don’t know what to do. Do I just stop sharing my emotions and worries with him? Anyone else been here? TIA ❤️
