I think oldbatty, that there is both good and bad on youtube, it is really helpful to get a pointer to videos which are by reputable people whose videos will be useful rather than waste time looking at those which are not. Things found on the internet are a mixture of good, bad and everything in between, but so are books. Good videos by trusted professionals or volunteers who work in the field are a great way of helping people, free and easily accessible. Sometimes it is just knowing which ones to look out for
Selfish behaviour is nothing new, sadly I'm sure many like me will have encountered it in our generation and in previous generations. Maybe some young people do mellow with age, so we see less of it as people grow older, but not all do. My own ex-husband was always me, me, me, an abusive narcissist, although not officially diagnosed, there was nothing wrong with him, only time he ever saw a counsellor was because he had behaved very badly at work and had been observed, so booked himself in before he was disciplined so he could say he was doing smething about it; he told me what he'd said to him which was very deficient in its scope and based on what he told me, not awfully true, and if what he told me that the counsellor said was true, he ought to be struck off. He hated visiting my parents; when we were there, he'd make sure that we spent as little time as possible there, going out and doing things that he wanted to do, and wanted to do it as little as possible. He also hated it if I went on my own or with the children, and they were too far away to go unless we were staying, so I could never just pop round. It's a tactic of an abuser I now realise, to isolate you from those who might notice things were wrong and help you. His father was very selfish and self-centred, as in a different way was the grandfather of his that I knew. His mother was very self centred too in a more passive way, maybe to help her cope with 2 difficult men, who knows.
