Is it normal that i really despise my friend?

For the last 9 months I have felt 1000% done with this friend.
She is always doing one of the following:
-Playing victim, usually about the smallest thing i.e still goes on about an ex who she hasn't got over from 2 years ago, and they were only together 3 weeks.
-Talking about which new guy she works with/met in a club/ glanced at in the street is now desperately in love with her
-Talking about how great she is and how her boss/ anyone else has commended her about something
-Talking about how her job/work out routine/whatever else is so good, a lot of the time not really knowing what the hell she is even talking about
-Flirting with any guy she can and then complaining that all these guys like her and she doesn't know why
-Doing something for someone else purely to receive praise and then having a cry if she doesn't get the praise she feels she deserves
-Making huge announcements and promises purely for the attention she gets
-doing something really reckless like hard drugs for attention and once people stop giving it to her she completely stops
-Or lying about any or all of the above

As to why I ask if I may be jealous- she is very pretty and she has a niceish body, and she seems really sweet and nice when you first meet her. Once you get to know her and the ugly comes out you start to see her differently, but remembering how I saw her before I knew her well I wonder if it comes across like I am just jealous.
Not that I need to be since I am very happy with myself and my life and my relationship.

What do you guys think?
