When forming a conditional clause with "if", when should I choose "if I am", instead of "if I were" or "if I was"?
I think was is never correct, but may be acceptable for informal use.
I'm writing a song lyric:
If, after life, I satisfy myself for feeling more alive,
will I still feel alive as if I'm breathing?"
Am I correct for choosing "as if I am"? Would "as if I were breathing" be better?
