high school

sooo i just entered to my new school and i dont have new friends

basically i just passed to 10 grade so i started high school  (im not from the us) and some of my friends also go to this school so i'm not really lonely, but i dont know anyone in my class, i do talk sometimes with the girl beside me but she is friends with the other girls in the table

i really want to make more friends specially cause all my other friends (from my high school and and my other friends from other schools) already have met a lot of people

i'm a really really really shy person, and also get embarrased from everything and i try to speak but i just cant :(( but i do think i am a good person and can be an extrovert with people i talk often to

so i would appreciate some advices on how to speak with other people 

i really want to be friends with my classmates
