Well it won't make any difference to life but it's a huge psychological thing.
Its only a huge thing because you allow it to be**
My advice for what its worth is... switch whatsapp group sh*t off and get on enjoying your own life.
**easy for me, I have (in adult life) never celebrated christmas.
BTW like many on here, I was married at 21 and had a child at 23. Your son is not a kid any more.
If he has issues, as people of any age can have, get him home and sod what the village idiots say on the pathetic group chats.
My opinion only of course.
I wish you the best.
