Ton, sorry to read about that. I’d like to reiterate what others have said: do find someone to talk to and if you don’t have someone, do take up the offers here. Don’t hang around, just do it. I do fear that, as others have said, the loss of community makes people feel considerably more vulnerable and there is a lack of peer support.
Last September I set up a dads group when junior started at primary school, because it seemed to me that dads walk in the shadow of the mums during school time. My hope was that dads would have a group to meet up with each month for a beer and some grub and shoot the breeze, have a bit of banter, but also talk about the kid(s) and any issues at school or otherwise. Word has already got around with someone saying they wish they had a dads group.
