i help make peoples lives better

I help make peoples lives better talking on here. helping them with their problems. then they vanish. two examples. averageman he is being abused by his dad in multiple ways and I help him find ways to get his dad to treat him better by taking up weightlifting like his dad wanted and getting him to take up wrestling as dad wants him doing sports. then he goes totally silent. other guy is hello friend. I get him into lifting more and dressing better and awesome emails with him saying how much he likes getting emails from me each day and how much he looks forward to each message and likes me a lot. then he suddenly blocks me for no reason. I been reading our messages over and over and over and everything is fine in them he likes me a lot. I was always nice and helpful with him. so what do I do? just give up on helping people and give up on comeing on here???
