10 year son has lost his friends

[OkPedro]

Please bear with me on this one, I am so upset this evening. My son came home from school today and told me his 3 friends have told him they don't want to be friends with him anymore. My son is 10. He's lovely, sensitive, funny and thoughtful however he is a very difficult child, he cries over everything if something doesn't go to plan, if he doesn't like the way a game is going. He cries when he's tired, hungry and frustrated. Full on break down crying.. He's always been this way but he can have a few weeks where he's calm and I can talk to him about anything without him crying. And now it's affecting his friendships. His closet friend told him today he doesn't want to be friends anymore because "You cry about everything, you don't play fair unless the game is going your way, you are constantly telling tales to the teachers"
I could cry for my son clearly this has been building up for awhile and his friend's have had enough now. What the hell do I do to help my son? I have an older child she is 13 we've had the usual ups and downs with friendships and I've shown her how to sort it out herself.
I don't know how to make this better for my son

Is he upset? I would use half term to give it a break and think of triggers and resilience strategies. Most kids of that age can control impulses and emotions, empathise and adapt behaviour. If he has always been oversensitive have any additional needs been considered?

Honestly, this might work out for the best in the long run. He must be year 5 or 6 if UK? So he needs to learn now anyway , in prep for secondary. And his friends telling him is way more impactful than you telling him, so a greater chance of him making the changes. Plus kids are forgiving - if he can be seen to be trying they’ll recognise it. So you help him make the changes, and by the time he gets to secondary he’ll be in a much better place for long term success. You don’t want to go to secondary and be known as a cry baby. One of my DS’s friends was like this. And tolerance for it definitely wained as they got older.

Thanks for your replies.. Yes he was upset, he told me he told his friend "I'll try do better in future" fuck sake 💔 but yes he has needed this to happen. I haven't had a proper chat with him about it yet. I spoke with his friends parent and she was sad for my son that it's come to this but I told her I don't expect her son to be friends with mine when he doesn't want to..

No additional needs..he does really well in school and I have no other worries about him.

I'm in Ireland he won't start secondary until 2024. I'd be more concerned if it was sooner hopefully he has time to turn things around.
