to feel jealous that a friend has come into a lot of money

[Anonimouselee]

Struggling with feelings here. Friend has come into a lot of money. Enough to pay the mortgage off with the same again coming down the line. They totally deserve it, is a lovely person and a great friend. But... I just feel a bit crap. Making me question our huge mortgage, life decisions, career choices. Others must experience this...? How do I get my head around it?

Of course it's fine to feel jealous. Absolutely everybody would.

However, sensible people wouldn't show it.

Well that depends. Could be pure blind luck in investing in something at the right time, could be paying into a low risk fund for years which has now come to its expected fruition.

If it's an inheritance I can tell you I'd much rather have my dear Mum back instead of the money I got. Think about it.

It isn't even an inheritance anyway, OP said so.
