I am after some help this last week my autistic son had an overdose at his father's place. I took him to the hospital where he was discharged about 6 hours later. The next day he collapsed on the side of the road so had to call an ambulance to take him back to hospital because I was concerned for his welfare. He had stated to the hospital staff that he was still feeling suicidal but they discharged him about 8 hours later. I tried my best to keep an eye on him and even removed most of things in my house that he could use to hurt himself. He overdosed again which I woke up to him doing I took him back to the hospital. He had to be put on a machine to help him breath. I have been told there is a major investigation as to why they let him out when he was still feeling suicidal and told them that he wasnt going to promise he wouldn't do it again. The answer I received from the hospital on his second discharge was that he has outside support and there was really nothing more they could do for him. Is this medical negligence on there behalf? I have been told to get a lawyer any help would be grateful thank you for your time.
