Advice on how to adapt

Hi my son was diagnosed with asd in March this year after spending time in an institution for depression and since he was discharged life has been hell in the house. I have been told I have to learn how to deal with him but he's 16 and won' listen or be cooperative at all...does what he wants and shows no empathy. I get very down and upset but he just show nothing and I've tried to just be like him and show no feelings but it' so hard. We don' get no help and I don' get no rest bite as I'm on my own with him. 

Is there anyone in the same situation that can give me advice on how to deal with a teenage boy with ASD aspergers...i seem to have obly 2 options send him away which I'm not doing or live with it....

Thank you
