<human>: F (21)/F (21)
So my best friend's a wonderful gal and I love her and she loves me, yadda yadda. Thing is though, her competitive nature is beginning to drive me INSANE. I'm what you call a pretty laidback gal. I understand that a little competition can be fun and even healthy at times, but when I'm hanging out with her, I'm beginning to feel like I need to be on my guard all of the time. 

For example:
I'm telling her a story about how some cute dude hit on me at the bar, she then (always) states that he really wasn't that cute and that a cuter guy was hitting on her.

I mention that I'm no longer going to go out on a run and she gives me a smug look and actually says, "yea, didn't think you had it in you."

My friend was like, "Becca, (me) you cut and style hair really well!" And she was "Yea, I guess, but I wouldn't ever let her touch mine."

She tries to make jabs at my body, despite that I'm 5'10, thin, have perky breasts, long legs, and a great ass.

I'm half black, and she drunkenly once said that "people just typically don't find blacks to be attractive...........but you're hot."

Can you summarize the given text in a few sentences?
