I'm killing my succulent! Can someone green-fingered help?

[MyFingersArentGreenAtAll]

I know absolutely nothing about plants.

I was given this succulent about a month ago and it was green and lovely. I watered it a tiny amount when I was first given it.

The label on it said to water it once a month, and also said that it would be normal for the bottom leaves to shrivel up.

After a week or so, the bottom leaves did start shrivelling up and turning yellow, which i thought was normal. But then more and more of the leaves did, so I watered it after 2 weeks another tiny amount.

The leaves have continued to turn yellow/shrivel and now, one month later, the succulent looks like this.

What do I need to do? Can anyone tell from the photos if I'm underwatering, overwatering or not giving it another sunlight? Because I've got no idea!

Someone save my succulent, please!

I fill its tray about once a month if I remember to
but yes they like to be VERY dry
they grow in sandy gravel in the wild

For yours, knock it out of its pot and put it on a south facing windowsill
let it dry out for at least a month
then put it back in the pot and try to forget to water it

Does that pot have any drainage holes in the bottom?

@ListeningQuietly Thank you, I will do that. I spritzed it with water as it was looking a bit dried out but I must have overdone it.

After you water it make sure it’s not sitting in water, drain it out. I also wouldn’t water it for a little while to let it dry out.
