I totally understand how scary and exhausting this must be, especially with the anxiety on top of it. Vertigo in pregnancy is real and common, but at 25 weeks with this level of impact on your daily life, it's worth asking your PD or gynae specifically about what's causing it and whether there are safe options to manage it better, sometimes it can be helped with certain positions, hydration, or even medication that's safe in pregnancy. Have you mentioned to your doctor how much it's affecting your mental health and daily functioning? They might have more targeted solutions or even refer you to a specialist if needed.
