Visual Vertigo and restarting practice

Hello – I apologise if this is a bit long but I’m hoping someone can give me some advice 🙂
I bought the Masterclass programme a few years ago as I live in a rural area and there are no classes near me. I was getting on really well with it until I broke a small bone in my foot. After a few weeks, I returned to practice, and then developed a sudden onset of vertigo. Initially, I was diagnosed with Labyrinthitis but the condition worsened to the point where I had to used 2 walking poles to help me stay upright. After investigations, I was diagnosed with Visual Vertigo – my brain uses vision preferentially for postural and space orientation control (that is, I need to see to know where I am in space!). I have done a programme of vestibular rehabilitation exercises and been told by my ENT specialist to challenge any movement or situation that induces vertigo. I am much improved – though it has taken a couple of years, and my poor body is desperate for me to start exercising! I walk but any fast moving exercise such as badminton is still too much for me.
So (finally, I get to the question!)I was wondering if you would advise me to start with floor postures only or to take one posture at a time until I get comfortable doing each one? I have attempted Sun Salutation but fall over most times on the forward bend, although I am fine with all other movements.
Many thanks for your time 🙂 Sarah
