High risk pregnancy and he said i could die...?

I'm 6 weeks pregnant and had my first appointment today ...I was so excited and then was told he will not be my obgyn that I'm too high risk and have a very high chance of my 'demise'. I had blood clots in 2007 from birth control, I have bulging disks in my lower back (he said I couldn't have an epideral and a c section is out because I could bleed out due to the blood thinners id have to be on) and also I'm considered very overweight. I'm terrified and I want to have this baby. Has anyone else ever had or know of a situation like this? What do I do? I'm only 23
