You say 'I was gonna' when you're thinking too much, like your brain is exploding and you're barely holding it together.

I was gonna say something, but my brain exploded.

I was gonna tell you the truth, but my brain was too busy exploding.

I was gonna say I love you, but my brain turned into a cockroach.
