i feel like i want to change my identity?

fisrt of all im sorry for my bad english. im an 18 years old guy and i have social anxiety. not so long ago like about 1 month i started college and i have made awkward and shy impression to my new classmates, there are 3 pretty cute girls in my class and they are nice but when i talked to them face to face i just cant im so nervous... when i see them walking towards me from a distance i feel like i want to explode i get panic immediately... and i have made a mistake i talked over two of the my girl friends and they seems really nice usually every girls that i know before hates me when they see me looking anxious and weird but two of my girl friends im college dont hate me... even though ive been so anxious around them and they know it for this one month and i never talked to them before / outside of text i have made a mistake because in text i talk very comfortably with them now im so anxious about the next monday it'd be weird if i still get anxious around them because ive talked so much with them on phone oh my good i dont know what to do
