The song “what doesn’t break you makes you stronger” springs to mind Alex and your positive mental attitude has made you very strong.
Parts of this I can also relate to “teachers telling me just get married and be a wife as that’s all I’ll amount to” because I also had a long term illness.
I metaphorically put two fingers up to it and carved my own way just as you have done.
Well done you are an inspiration to those 11 year olds in your care now. Be very proud of yourself x
