OCD is common to overlap with autism as well as sometimes, it is fixed thinking of autism
and not ocd. WITH
autism, especially that has never been diagnosed, autistic burn out can happen
and it is debilitating. It requires almost complete removal from life in order to get over it. There is regression in skills and abilities, feels so awful and very much like a depressive spiral. It can last years, unfortunately, if one doesn't know what it is and some skills are harder to get back after.
