It's somewhat embaressing

[Baudelaire]

I laugh like REALLY uncontrolably, at ANYTHING, and I seem like a clingy little freak with no personality, how do I break this habit?

You could try controlling it? There's not really anything wrong with being overly energetic it's just sometimes, it can get a little annoying. Yeah, just try to hold back a little and you should be able to stop soon. Good Luck! :)

Ughh I hate that feeling like you have no personality, I felt that way for a long time. I still have a bit of a reputation as I "laugh at everything" it's just a subconscious thing.

Try and control your feelings and the laugh and power through, that's all I have known to help with this.
