Check in with yourself, are there parts of your body that you can move? If your legs are ok, starting with walks, maybe hands-free yoga classes. If just your upper body is ok, then doing chair yoga or yoga that only works with the upper body.
Find movement that you can do and focus on that, even if it changes day to day. Sometimes a dance party to your favourite songs can help mentally and physically. Moving even just for 5 minutes, and easing your way up to 10, 15, 20 and starting to notice what feels ok in your body can be extremely empowering.
If movement really isn’t something accessible to you, meditation is another “limb” of yoga that you can explore! There are many fun and creative meditations out there- my favourite is a body scan where I can check in with my physical and emotional body.
