I wasted £50,000 in 3 years I’m 24

My mum passed away when I was 21 and I got £70k life insurance. Obviously I was extremely depressed at the time and feel like I’ve only just come to terms with what’s happened (I’m 24 now).

I realised the other day that I’ve somehow spent £50,000 and have nothing to show for that money. Has anyone else done something stupid like this and does anyone have any tips on how to make myself feel better about it? 

I want to live comfortably when I’m older and feel like I’ve wasted a huge amount of money.
