Why am i like this?

Today i heard my friends talking on discord about going out, but they didn’t invite, and that made me wonder: why? We often play games on discord but we know each other in real life too, and even though i am a girl and i share interests with them i know i will never be “one of the boys” exactly either. I don’t have that many friends, maybe 4, that I know i can rely on, or I can be open around them. I am having a hard time keeping and making friends, and the rest of the people i know i consider them more like acquaintances or occasional friends. I am aware that i can be somewhat difficult, i am quite blunt, i cant express my feeling properly, i am terrible at talking through messages or using emojis, and i can’t control my facial expression at times (my default expression is one of pure boredom and disinterest)
I am trying to talk to people and form relationships (even though it is scary and i am an introvert) with them, but it feels like am talking to walls at times. At the beggining of highschool ( two years have passed since then and still no progress ) i tried talking with my classmates, but none of them seemed interested in talking back to me, I am quite anxious as well and don’t want to seem intrusive or annoying.
I always wait for other people to text me or ask me to hang out, but they almost never do, especially new people.
My life is boring and repetitive and sometimes i am perfectly fine with that, but other times it just feels lonely, everybody tells me to go out and enjoy my life while i am free and young, but they never consider how much it hurts wanting it, but not having anyone to do it with.
So my question is: how can i make people see that i want to go out, talk to them, and make relationships last and find new friends?
(Sorry for any bad grammar btw)
