How the fuck are you spending 10 quid on spices?! You can get a good few for 5 at Lidl or Aldi.
Also, having been someone that poor, people in that position should understand spices and at least have a few of them because it was one of the few things that kept me going that at least my toast and tinned veg & hotdog pasta both had some flavour.
I don’t know who needs to hear this, but:
It’s ok.
You took action to remedy the immediate problem. That’s a huge step.
Now you’re grieving for the current state and how it could have gotten this bad. It’s ok to cry and accept that your past self made mistakes, when you’re able to you should forgive your past self. Take as long as you need to do that.
What comes next is getting to your feet and just fix it up a little. Doesn’t have to be a lot and it won’t all get done overnight. All that’s needed is just 1% everyday. It’s ok to take a break, it’s ok to go slower, but a little progress everyday and you’ll get there.
