re; post by Ivykaty, 'I was getting called to the school because his anxiety causes him to be inconenant ( can never spell that word) and a mainstream school are not allowed to deal with that, due to child protection rules'
I am a TA in a mainstream secondary school. I work with SN students with a wide range of complex needs, including several with autism, downs, fragile x and complex medical/physical difficulties such as paralysis and yes, often dealing with hygeine and continence issues. Never been a problem, despite the school being a VERY large one with over 1700 students.
The school is also part of a federation with a nearby Special School, and once a week a TA from there brings in students from her school into mainstream classes in my school. She is also the parent of one of my students who has moderate learing difficulties.
As for the OP, I'd suggest that when you feel ready you look into working as a TA, as you have the perfect experience for this work. It fits in well, and most schools are very understanding if you need to sort out personal problems.
