Why do I want Reese’s now?

Before my eating disorder developed I was never a fan of Reese’s. They were always last to go of the Halloween candy and if I was offered one for free randomly I’d usually deny. Now, Reese’s are one of the things I commonly crave. I first thought it’s becuase I don’t eat a lot of sugar, but my intake mainly consists of fruit, which has natural sugar (not the same thing I know but still). But also, if I’m craving sugar, why is it Reese’s and not a candy I actually like, like sour patch kids or Twix. I really don’t even like peanut butter to be honest. I just find it weird and if anyone has a clue why or experiences something similar please let me know bc I am curious
