Yoga retreat deposit marked non-refundable and I twisted my ankle — any chance of credit or is the money gone?

Written non-refundable usually means cash back is unlikely, especially close to the start date — but many small retreats will still discuss a date shift or credit if you send a clear doctor note early and stay polite. Ask for what you actually need: move to a later week, transfer to a friend, or a partial credit toward a shorter stay when you can walk. Do not demand a full refund as a moral right if you signed the terms; ask for goodwill options. Screenshot your medical advice and keep the thread in writing. Outcomes vary by host — some say no, some offer credit within a few months. I will not invent percentages.
