I don’t know what to do.

I’m 16 and a Junior in high school. I’ve just felt pretty lonely since me and my boyfriend of 5 years broke up. He’s already got a girlfriend and it’s just been really hard to move on/ get another boyfriend/girlfriend (I’m bisexual). I’m kind of a homebody but I like to meet new people. It’s just hard seeing couples at school and you’re all alone. Before anyone says anything, yes I focus on my grades and they are good. If you have mean things to say then don’t comment at all. Honestly I just want advice on how to get someone new or love myself...Or something.
