@calicoday hey thank you so much! they were truly arduous days, but very much worth it.
do you have any physical illness? I'm sure the team would be happy to accommodate, it might be good to reach out to course management. the point is NOT to torture yourself.
if you can sit for 20 minutes, I'd recommend the mini anapana course https://www.dhamma.org/en/about/mini_anapana
happy to chat about this if you have any questions! all the best 🫶
