What should I do?

Hey, I really need some advice. My best friend and I signed up for this camp, but lately, when I tell people about it, they react with "ew" or say it's for weirdos. The camp only has 20 people going, which is making me feel insecure about my choice since it’s associated with some odd reputations. I’ve been thinking about it for days, and it’s really overwhelming me. I talked to my friend about my concerns and mentioned that I might not want to go, but now she’s guilt-tripping me because I encouraged her to sign up. On the flip side, a not-so-close friend suggested I join her camp, but she’s going with two of her closest friends, and I’m worried about feeling left out. However, that camp has more people, and I could potentially make new friends. If I choose the other camp, I know my best friend will be upset. What should I do?
