Whenever I go to a party, I subconsciously choose an FP for the night based on who I know there the most (usually the person I go there with since I won't go to a party where I'm not sure if I know anyone)

Problem is, I get too clingy and follow them around everywhere like a dog on a leash. If they are having a conversation with someone, I stand near them awkwardly waiting for them to finish etc. It's cringe and embarrassing. I don't know how to socialize besides the people I already know and this makes me turn down partying even though I want to go out there and live life. 

I am my own person and I don't want to show otherwise.
