"Get" and "Go"

[Mr.Lucky_One]

Which of the clauses below are correct ones and which are incorrect ones?

1) It got cold. It went cold.
2) Don't go crazy. Don't get crazy.
3) The weather got bad. The weather went bad.
4) It's getting worse. It's going worse.

Could anyone tell me about using "get" and "go" as linking verbs?
When should one use "get" and when "go"?

1) It got cold. It went cold. "It got (became) cold" is correct.
2) Don't go crazy. Don't get crazy. Both are OK.
3) The weather got bad. The weather went bad.
4) It's getting worse. It's going worse.

Mostly you use "get" where you could also use "become". An exception is #2. I don't know why.

Thank you.
And what about sentences #3 and #4? Are they both correct? Do the sentences in each couple have the same meaning?

The same applies to 3 and 4 as applies to #1.

And is there any other linking verb that can substitude "go"?
