I am having a mini panic attack about my sister's wedding and need some advice. I'm her maid of honor but we don't really get along — the only reason she asked me to be in her wedding is because I'm her only sister. We just had the bridal shower, which was fine except for behind-the-scenes drama with another bridesmaid, but now I'm worrying about the bachelorette party.

I am a teetotaler and will be the only one not drinking at the bachelorette party. Since I'm the MOH, I'm the one who is supposed to plan everything, but I just don't feel comfortable being around alcohol all weekend. My sister and I have a very strained relationship as it is, but I feel like she'd almost have more fun if I wasn't there. Can I back out of the bachelorette party? Would that cause an even bigger rift than we already have? I just don't know what to do!
