Is this a kind of paranoia?

When my mood gets elevated I start getting really strong thoughts that my fiancee is hating on me. I start interpreting her tone, her pauses, what she's saying as being directed at me in a negative way. In particular, I think she's angry at me, and this pisses me off. I start feeling this really strong anger build inside me, and if I don't have enough insight to cut off our conversation I totally explode and start accusing her of being my enemy.

I wonder if this is a kind of mild psychosis. It's irritability, that's for sure. But my anger is based on this fantasy that I feel so strongly and can't let go despite good reason that I should.

I do not think it is mild paranoia. I think the operative terms here are "I start feeling this really strong anger build inside me", and "don't have enough insight". Since you do not have enough insight or self-control rather to cut off the conversation, but do fully realize that you are lacking self-control and insight, it is not psychosis. Is it severe irritability for which you need to tweak the mood stabilizing drugs. The prescriber should know about the high degree of irritability.

On the other hand, it does not matter what you call it, because the drugs would be the same (antipsychotic or antimanic properties of antipsychotic drugs are what's needed).
