How do you get past feeling jealous that your friends all have closer friends that aren't you? Or get over the fomo that comes when they all do things without you? 

My best friends all have best friends and I'm nobodies best friend. Two of them were at a birthday party this weekend and I couldn't help but feel sad that I wasn't there. I know the birthday girl but I guess not well enough. My other friends all have the same thing, each have a best friend. I just kind of wish i was somebodies best friend I think
