Hope you are feeling a bit better this morning, but it will take a good week or so to fully recover. Be kind to yourself in the meantime.
I am famous for my falls - and have been for decades. some have landed me in hospital for extended periods. Usually, just a good time to recover. I do not feel that I am particularly careless, but my 'fall history' would make it appear that I am.
As has been said, most falls result from tripping over something, or trying to rush to do things, or not using correct equipment (eg; using chair instead of proper steps, etc).
My last very bad fall was 18 months ago, and all I did was to trip over something as I moved backwards and sat down heavily. Was in a public place and highly embarrassed, knew I hurt my already painful back - I was an official and did not feel I could pull out, so with the help of strong painkillers I always carry with me managed to get through the day and even drove myself home. However, by the following morning I was in agony and told my daughter who came over that 'I was too ill to go to A&E'.
So, it not until two months later that an MRI showed I had a stress fracture of the spine!!!
