You're not bothering me. I do recommend either Uncomfortable Overhaul by roBurky or Uncomfortable Changes from Zerbu, as both of them (although you only want one or the other) use Uncomfortable to boost other negative emotions and will result in exactly what you're describing. Even then, it sounds like you may not have encountered some of the other moodlets that can randomly pop up (sad, angry, tense, embarrassed are all in there, along with happy, inspired, even flirty!) which can result in even stronger results than Biological Changes.
