explanation needed

[saym]

Hi,
Can someone help me with the following sentences. I need to know exactly which grammar rule is being broken in the following sentence.
1. I have in debt.

2. It is important to don't worry.

Now in the first one i know it should be 'I am in debt.' And in the second one it should be 'It is important not to worry.'
All i need is a grammatical explanation.

#1 is not about a 'rule'. It is simply that in English we BE (am/is/are/etc), not HAVE (have/has/etc), in debt. We can HAVE a debt/debts or BE a debtor.

#2. We use the auxiliary DO to form the negative of:
the present simple: I go, I don't go
the past simple: I saw, I didn't see
the imperative: be, don't be.

We don't use it for the negative of:
the gerund: I enjoy working, I enjoy not working
the infinitive: to be or not to be

Or,

I am _____ in debt.

I can't help feeling that fivejedjon would have appreciated your thanks more if you taken the trouble to write the word in full and capitalised I.
