When you have BPD, the perpetual mood fluctuations and intensity of emotions can feel like you’re riding on a roller coaster blindfolded. One minute you’re on the rise, then next minute you come crashing down, and you never know which way you’re going to be pulled next. And it’s scary and dangerous, because when you’re in the trough, you come this close to acting on the impulse to do something reckless and self-destructive. Then in the next moment when you seem to be trekking uphill again, you’re momentarily glad you didn’t do anything drastic after all and wonder why you were wanting to do so in the first place. Except for the times when you do, because even when you know that the roller coaster will climb uphill at some point, you don’t think you could bear another steep decline and you’re desperate to get off. Then you feel yourself start to dip, and it all happens all over again. And it’s frustrating, because you want to go on the carousel or Ferris wheel instead, something a bit more smooth riding, or if you’re going to be on the roller coaster, at least be in control of the car. But you don’t know how, so instead, you’re stuck on a ride that’s a bit too fast for you, with massive mountains and twists and turns.
