Feeling increasingly overwhelmed with added appointments, additional medical "scrutiny"

I'm almost 30wks pregnant, 5'7" 238lb prior to pregnancy, now 248lb. I was diagnosed with gestational diabetes a week ago. Ive been monitoring my blood glucose and increasingly freaking out about all the additional medical interventions heading my way. My meals have been fine, but my fasting numbers have been consistently borderline and I'm expecting that ill at least need overnight insulin.

But since that diagnosis, I had an appointment with the "diabetes educator", and now bi weekly followups with her in addition to my bi weekly ob appointments, and then they're going to add additional NST/BSP appointments too.

The more I think about the actual logistics of giving birth, needing to go to the hospital to be induced, then needing a c section maybe the more I'm freaking out. I'm feeling incredibly vulnerable and like I'm just being told what's going to happen. I went on a hospital tour this week and i just felt like crying the whole time. ("Induction at 39weeks or sooner, clear liquid diet only in the hospital, 9/10 pts give birth on their backs, we don't let anyone use the birthing tubs anymore").

I have a history of military sexual trauma, and i was already scared to get an epidural because the thought of being confined to a bed unable to feel my legs or move while strangers touch me felt unbearable.

I already see psych, and a therapist, so I guess I'm just ranting here. How have people coped with changing plans/medical status?
