Diabetes 🙁

My names haylie i have a two year old son with his pregnancy I didn't have diabetes I was fine I had borderline preeclampsia but that's it nothing else but a healthy pregnancy ... This time around I got pregnant unexpectedly and it's twins boy and girl twins I'm due Nov 3 I'm currently 25.1 weeks I see my ob and maternal fetal medicine Dr as well . Today I found out I have pregnancy diabetes 😭 and I honestly feel like complete crap and feel like this is my fault 😔 Im a plus size mom weighing 337 pounds ... I started off at 310 pounds now I feel so fat and upset lots of emotions on top of this I might as preeclampsia I had everything that fits it's qualifications except protein in my urine this pregnancy has been so hard on me with having hyperemesis gravidarum as is
