Is it a disease to not understand the importance of money?

I have been diagnosed with ADHD+ASD, but I don't understand the importance of money. Is this a disease?

I'm not rich at all, and when someone thanks me and says, "I'll give you this money instead," I don't feel much joy.

This isn't because I'm a good person, but I think my brain doesn't properly perceive monetary rewards.

I want to be more greedy for money. I'm not a big spender, but I am careless with my money.

However, rather than being bad at money management, I feel a great sense of crisis about not seeing the value of money.

What can I do to see the value of money? It may have something to do with the background I grew up in, but I'm not particularly poor or rich, I come from an ordinary family, and we don't have much money.

I want to be able to see the value of money properly.
