Help I am charming, and intelligent, and have great manners, but I fell like a boring date?

I am charming, I am very intelligent, I have good southern manners, but I feel like pretentious, narcissistic, attitude is keeping me from having a good relationship, I tend to talk about myself, I tend to think of myself as better, and so it makes people bored of me, I don't have many friends. I think it's because of the fact that I am very into myself, and that I speak Deutsch, French, Italiano, Svenska, Nederlands, and I am now trying to learn Russian. I am a ballet and ballroom dancer, I play the guitar, the piano, the clarinet, and I am studying to be an Opera singer. I feel like I must stay true to myself, but I go to extremes, I hate how stuck up and snobby I can be, it disgusts myself sometimes, the things i say or act towards others. I need help cause it is messing with my love life, or lack there of.
