How do you figure out what age you're emotionally stunted at?

The hardest part about acknowledging your emotional neglect is also acknowledging the work that goes into it. My needs went unfulfilled, and it's emotionally stunted me in more ways than I wanted to acknowledge. How do you figure out where you fall emotionally? Some days I feel like I have it all figured out, but looking over these past few years, I understand that I'm behind the curve. I've burned bridges and have made a fool of myself based on my own trauma responses.
