...need advice?

hey everyone. This is my first rant I think orz.
I just feel emo lately.
I know the causes: my mouth

Yea I got such a filthy mouth here. I cant keep it shut. I just want to, but it's kinda hard. Apparently, when I shout something odd in twitter, there's someone who felt insulted by my shout. I know I didn't mean it, but that's make me feel guilty orz. This thing happen since I was junior high school, and I admit it is a bad habit. I really want to know what should I do with my mouth. Should I tear it apart?

Or it just because my personality?

I'm a sensitive, rude person (I think)
lol this is a real problem.
I just need someone's advice pls. Should I become more hikky than before?

Urgh just a useless emo rant orz
