Anyone else scared that their friends only hang out with you for access to your cooler friends?

Ever since I was a kid, I've never hung out in groups because all my friends and I had individual relationships and I was scared that if I introduced them to each other, that they would get along better than with me, talk shit about me, and leave me behind.

I feel like people only see me as an opportunity to get closer to my other friends who are much cooler than me, and I feel like I might get used, like some stepping stone. I know I might be being crazy, but this has caused me to never integrate my friends in any way. Which causes people to think I'm shady or mysterious when in reality I'm just scared.
