Need advice please!

I have an extremely high risk pregnancy and see a high risk specialist and a regular ob. One of my risks is 5 previous classical c sestions (up and down)this will be my 6th and last. I'm at risk of uterine rupture as well as having placenta previa and very likely placenta accreta. My maternal fetal medicine doctor says I will need a hysterectomy and bleeding is a major concern of his. He also says I can be delivered no later than 35 weeks but is worried baby could come anytime from 25 weeks. I'm 23 weeks now and have a history of premature delivery. I want to have my final csection the way I have always been cut. I dont want multiple incisions to my body. My previous children were automatically delivered this way(3 by a specialist)without me even asking or mentioning. I was told it was wrong to cut me side ways since I already had such a large incision from the first section. My ob disagrees completely and says she doesnt understand why in the world those doctors would all cut me that way and no one does csections like that even in emergency situations. She wants to do the bikini incision and also blows off nearly everything high risk says. Especially about baby being born early. I spoke with high risk and he tactfully said he would normally agree with her. My classical incision is harder to heal, more painful and more risk of infection but due to my history and risk and my need for a hysterectomy at birth to control the bleeding that she will need the room my classical incision will give her to work and so I need to have a final classical cut. I'm so upset because the one thing I shouldn't have to worry about right now is the birth and it's all I do worry about. I'm terrified to have a csection done by someone who isn't listening and just keeps saying high risk doctor is being overly cautious. It seems late to find a new doctor and not sure any doctors will take me for being so high risk. The first ob I seen this pregnancy referred me to this one after she refused me for being "a severe risk of morbidity and fatality". My high risk doctor very rarely does deliveries anymore and I have no idea what to do at this point. I'm on Makena injections to try to prevent him coming early but high risk is still very concerned he will and I'm terrified of my surgery if I do. I've left so much more out due to glow resetting after my first attempt. Any advice or thoughts would be very much appreciated. I'm not supposed to be stressing but with everything I'm dealing with it seems to be all I can do.
