I feel so lonely

I don't have a best friend outside of my family. The only person I have like that is my sibling.

I feel like crying everyday because I dont have close friends. I just moved from Kentucky to Florida last summer.

I lived in Kentucky my whole life, had shitty friends there, but at least we were close.

Now that I have better judgement, I've made friends with better people, but we're only friends cuz they're nice to me. We have nothing in common.

At all.

I just feel so lonely. I dont act on it, but I do get very jealous when my sibling hangs out with other people, talks about her amazing friends, or anything like that. I at least get a little jealous.

But like I said, I dont do anything about it. I let her be happy, of course.

How can I fix this?
