MY son is becoming adamant. He donot like to attend to any household work.?

My son is around 23 years old. He is my lone son. He is an engineer in electronics. He completed his engg two years back. After engg he went to canada for an advance diploma but could not continue there because of ill health, even before going there he was having depression problem. but we thought that it got cured after medication but after going to canada again depression creeped in and more over he could not bear the atmosphere there. He came back without completing his studies there. He also had a sex encounter in canada but luckily did not get HIV. He stayed in canada for eight months. Since beginning he is a calm going boy. He is sensitive boy. He wanted to go to UK but because of lack of funds and also because of lack of information I could not sent him there subsequent to that he insisted for canada. Now he blames me that I should have sent him to Uk along with his friends. He was being treated for scortal pain. He was also being treated spritually for his ailments. Now he has become adamant. We are giving him medicine for cooling his temper. He is not taking medicine we have to mix it in some food. He says that he was not given much liberty. whereas in my view he was given much liberty, during his elevnth and twelfth and also engineering he was given full liberty of going out with his friends. however during childhood I wanted him to give much attention on studies. as such I insisted him to be at house and to play after completion of studies. As I will be busy with my job I wanted him to attend some house hold works. some times he is attending but with resistance and telling that I should not tell him any house work. I have purchased one vehicle for him which he is using. He is arguing with me a lot when I am asking him to attend some work. He want me to do every house hold work and he just want to view internet facebook site. most of his time passes in veining internet facebook site. He will be attending one course on embedded systems from next month onwards. I told him to select such an institute which should be the best he says that the institute which I have selected is the best. He does not talk to me in an adjestive manner. He always talks in adamant manner. I want he should listen to me and his mother and also he should be adjustive in nature. He should understand that the work relating to house is his own work and that parents have done enough for him. He should under stand that now parents require rest and he has to take care of every thing. I want him to be cool and practical. He should act after understanding things. He should talk after listening properly. In case if there is a difference of opinion he should explain the merits of his opinion to convince us. How it is possible.He doubts that his father mother are his enemies and are doing some black majic upon him. He has one freind left in the city all other freinds have gone to Uk. He meets that freind very frequently and that freind says that there was problem with his nature as he was depressed but now he is almost normal. He selected Electronics in engg and now he says that he could have taken mechanical and my father did not gude me properly. He was offerred electrical first by the college and attended classess for a month in electrical but was so sad about electronics then I pursued and changed him to electronics. now he says that he should have gone for mechanical. He is waking up early in monring and going to walk alongwith his uncle regularly but critisizing parents who do not wake up regularly for a spritual meeting and walk. He has become too spritual and do not miss any prayer and think bad about those who do not pray regularly. some times when we talk to hm he will appear normal but when we tells him to do something he gets irritated. He talks to outsiders in good manner but with parents and his sister he is bad in talking.I want he should treat us with love and affection and should feel that we are his own people who like him and sacrificed a lot for him and that he should understand our feelings and act accordigly.
