How do I “raise my social status?”

I honestly don’t really gaf about it, but I feel like I’m missing out on so much, especially because it’s my senior year and I only have so much time left. My best friend gets invited to parties and stuff because of some of her other friends, but I’m not really that close with any of them. People at my school don’t really invite others to functions unless they’re close-ish. I’m not even necessarily unpopular, but I want to be a part of things too. :(
