Hi~

The original sentenc is like this.
-->Had it not been for my friends then, I wouldn't be what I am.

Can I change this sentence like this?
1. Had it not been for my friends then, I wouldn't have been what I was.
2. Had it not been for my friends then, I wouldn't have been what I am.

I think NO.1 sentece is correct?
is it possibe to write sentece No.2? what I am?
