I'm so nervous… how to calm down!

I'm so nervous.I just come from a party... was terrible.We left the house at 11.30 PM, we searched for a pub to smoke hookah and find the ''Element'', at the begining was a nice music, but after was oriental music, it was terrible because the own of this pub was an arab and he with his friend was interesting in my friends (Elena and Simona) but in me nobody,I felt uncomfortable, and we left this pub, at 01.15 AM after we were in another club ''Kanabis''where  was  more interesting, there we met  some old friends and we have fun for a hour. After Simona and Elena wanted to go home, and I was annoyed because I went just 2 time this year in the club.Oh, it was a terrible night. but i wish you good night <3
