You should say 'I'm going to faint' .
be going + infinitive:things that are on the way
Another use of the going to structure is to predict the future on the basis of present evidence-to say that a future action or event is on the way, or starting to happen.

Sandra's going to have another baby in June.
Look at the sky. It's going to rain.
Look out! We're going to crash!

Both are appropriate but the meaning is different.
'I feel terrible. (I think) I am going to faint' means you think you may faint but you are also not sure of that happening.
'I feel terrible. I will faint' means you have experienced this level of discomfort before, had fainted previously and you are positive you will soon faint again.

Fair enough-but I still think 'I'm going to faint' is more appropriate.
