I'm completely torn in between friendships.

I honestly don't know what to do. Both sides of my friends want to chill with me. I've ditched one for another too many times. This is why I don't like getting too close to people. I always have to pick one or the other. If I choose one side, people get mad. If I choose the other, people get mad. It's a lose-lose situation for me. What am I expected to do? I don't even know who to turn to anymore. I'm about to go to sleep soon. I don't want to deal with this anymore. I just wish I wasn't alone on this.
