You have married against their wish, naturally they will feel annoyed. Rather than attempting to talk to them desperately, give them some time to digest the fact. If you are happy with your married life, do not worry about anything at present. Try to make people around you happy. After few months try to be in touch with your parents, apologise for what you did but at the same time try to justify that you thought that you will be happy with him. Do not pressurize them for anything; just keep them informed about you. Over a period of time things will settle down.
