Triggered by playful sounds that my partner makes, leading to deep feelings of shame

I (38m) realize now that I’ve probably struggled with misophonia for years, but never realized until recently. The most apparent trigger that gets me constantly is when my wife makes certain repetitive/playful noises with our baby. Little rapid-fire kisses, or playful grunts or giggles. I have an immediate, involuntary reaction to make it stop often, like shushing or literally needing to pick up the baby myself, or simply walk away. The anticipatory anxiety compounds the trigger, because there are situations where I can just tell it’s about to happen, causing me to tense up, and then the trigger hits me even worse.

This trigger really lays an extra layer of guilt and shame on me, because I feel like I *shouldn’t* be triggered by them. I don’t want to be. She’s showing our daughter affection. But it’s just there and I can’t stop it. And then if it happens a lot over the course of a day, I’m just consumed with anxiety and shame. I’ve been talking to a therapist about it for a few months now, and have not made much headway on how to cope. Mindfulness practices can help slightly. Some weeks are just better than others. But others get real bad.

Mainly just curious if this sort of trigger is common to those with misophonia. I see so much about like chewing food, sniffling, and other noises that I feel are more objectively annoying and triggering. But I’d like to know if others struggle with triggers like this, that add that layer of shame and disappointment in yourself.
