My DH says school is just a horrible place that you get through to get out and that I’m worrying too much!
I’m a primary school teacher so I see the damage having no friends / being left out causes to children.
My son has ADHD although copes well in mainstream academically and is sociable but just hasn’t made any friends at all - he struggled enough in primary with friendships but I was able to help this somewhat by constantly taking other people’s kids out, spending lots of money and hoping it would follow onto a friendship - it never really did.
Now at secondary, all those primary kids have stuck together and my son has made no friends with any other group as they have all come together over things such as football training ( football is the one sport my son hates! ) or picking on other kids - mainly my son.
School are aware, they’ve tried various things such as a social skills group etc and the feedback is always good, that he is funny and well liked but this is only in the classroom / in front of teachers and then at break and lunchtime he’s alone.
He doesn’t want to move schools as hates change or I would have him out tomorrow but it’s heartbreaking to see him playing online games alone or with random people on the internet who then don’t bother with him again after a while or to see the large groups of boys heading to the skatepark after school and he is walking home alone 😢
