I concur with AntonTaro
The individual has surrendered themselves to the experience, but currently, they are in a state of suspension—experiencing those feelings yet unable to act on them.
It's a peculiar situation, akin to falling in love for the first time and just standing there, gazing, thinking, "Oh...this is what it's all about!" The person is succumbing to their feelings—whether they initially resisted them or they're the opposite of what they initially thought they felt. However, they're so overwhelmed and new to these emotions, so captivated by them, that expressing them becomes a challenge. Until the "download" is complete, so to speak, they won't know how to articulate these feelings.
