I totally empathise yorks'. I have this, mainly from family, but also from friends.
Mind you, I'm reminded of a quote from someone famous, but typically of me I can't remember who. Here's the (mis)quote and if anyone knows who it is do tell.
'Every time a friend suceeds, a little something insdie me dies'.
Then there was another one from possibly Oscar Wilde, but feel free to correct ...
'It's not enough to suceed. Others must fail',
Lastly, and I'm confident this was Morrissey, 'We hate it when our friends become successful'.
I reckon it's a nastier side to human nature which we all struggle to overcome or at least conceal with varying degrees of success.
