I'm too nostalgic. I'll admit it.

Our reading
An editorial interpretation.
The speaker acknowledges an excessive attachment to the past. Calling the nostalgia “too” strong recognises a limit that has been crossed, while “I’ll admit it” turns the statement into a concession. The line is self-aware about looking backward more than may be helpful.
