It's possible you're thinking of a different term, or perhaps you're trying to describe a personality trait. Could you tell me more about what you're trying to say?
For example, are you thinking of:
* Bubbly personality: This describes someone who is cheerful, energetic, and optimistic.
* Someone who lives in a bubble: This refers to someone who is sheltered from reality or who doesn't understand the challenges of the world.
* Someone with a fragile personality: This describes someone who is easily upset or offended.
Once I understand what you mean, I can help you find the right words to express it.
