Feeling Alone

I’m pregnant with my first baby and really struggling. It has been so much more challenging than I thought it would be. In my early 30s and 28 weeks pregnant tomorrow. This is the longest I’ve ever gone not drinking, smoking, no caffeine, no muscle relaxers or pain medication in general (I’ve had Lupus and RA since I was 15). I’ve also been thin my whole life and not handling the body changes well either even though I’ve continued to workout. My husband just carries on with life as normal, no sacrifices for him and not very understanding of my emotions. He’s made me feel like my pregnant body is weird and I’m crazy. I just feel alone in this and try to be rational and reasonable towards him. Am I crazy? Are these feelings normal? I’m so excited for our baby but pregnancy SUCKS.
