What does it mean 'you are too much'?

If someone is "too much" it usually means that the person using the phrase finds them too be a bit out of the ordinary, and a character in a generally entertaining yet unusual way.

It usually means that you are annoying, as normally after people say that they want to take a break. I have heared some saying it to me: was because of my extreme energy, talking enthusiastically all the time or asking the person to join me in EVERY thing i do.
