I am a single parent with a dear 19 year old son who has high functioning autism. He graduated from high school last year ~ which was great ~ but since then has not been able to get any type of work and is not interested in study (even online) or other. He does not like any interaction with people and hardly comes out of his room except for food and to go into the back garden. After many months of back and forth, I recently set up a dentist appointment for him and gave him an ultimatum of going (even with me via bus/taxi) and pulling his weight around more. Sadly he has decided that he would prefer to be homeless and is gearing up to leave home in a few days and go on the road. I am devastated and heart broken and do not know what to do. Before he would not agree to anything like therapy or even a simple walk in the evening. So he has decided against any help or intervention and I don't know what will happen now. He has made his mind up to leave and I do not know what to do. He is taking food and drink and once that runs out he said that he is not coming back and that is it.
