Should I

hi, need help...
I'm not really sociable, since I was a kid I was shy and it became worse with puberty. So... I have a few friends in my class, 2 to be exact and until now I never really felt the need to speak with more people in my class because I feel awkward, I'm not good at talking in fact, but there's that girl in my class(not a crush sorry to disappoint you) and I feel like... I don't know she kind of gives me the "you're not sociable enough" message when she talks to me without really saying it even if she said that I was the girl with only 2 friends in the class while laughing, once. Sometimes I'm alone with people who I talk to but not like a friends more like an acquaintance and it's just awkward for me and for them as well. I know I can be more sociable if I make efforts. So should I ?
no hate please
