School bullies

Having been sort of bullied at school (not like it is now) and also bullied in a different way at work (I could handle that now big time), the thing is that bullies are very insecure people who lack self-esteem so much that they need to diss other people to make them big in the eyes of their so-called peers. How sad is that. To retaliate against them gives them more fuel. To ignore them involves a lot of work from the soul upwards and this means they need to be with people who know what they are about, care for you, then tell you which is a foundation to work from, and they are the ones to tell you that you are a good person and to stuff what some others say.   

I was fortunate in one sense insomuch that I was born during the war and due to the early death of my mother I was brought up surrounded by ex-servicemen, both WW1 and WW2 who taught me how to toughen up and handle bullies, usually by striking the first punch.
Listening to a close relative with a 12 year-old son, bullying is much changed, indulged in by girls and boys and frequently involves postings on social media. The lad himself is being bullied this way and I'm completely at a loss as to sensible advice to give her. Anyone else come across this? Any advice you can share?

Bullying used to be so more straightforward in decades gone by. It was usually either physical, or verbal. When you left school on a daily basis, at least you had respite from it for the few hours at home.

The internet has massively complicated things. The bullying behaviour can get at you 24h a day, so you don't ever feel safe or away from it when at home. It doesn't matter whether you take steps to avoid it - other people will see it, and tell you about it when you are next in physical contact with them. And stuff posted online is there forever.

To be honest, I've just looked up some of the national charities who support children and/or their parents through bullying. Here are some of the links for how parents can support their children, but there are other resources on there too:

There is also ChildLine for the youngster, as one of the free chat lines (spoken or written) for support

I wish your relative and his son all the best.
