Scared and stressed

So today I went to L&D due to feeling lots of pressure well I found out my baby is breech so they did an ultrasound and I passed out on them (must have happened like 3 times) and they told me that is happening because my baby is so far in my chest her head is compressing against the main artery that pumps blood to my heart! Now I have to always stay sitting up even when I'm sleeping I can't even be on a incline or anything not to mention they explained how at risk I am of going into early labor since it has happened before and how that could be dangerous for me and baby! What do I do I'm scared very uncomfortable and very stressed
