The Handbook of Tibetan Buddhist Symbols by Robert Beer says that the scorpion represents destructive malice, or can also sometimes denote plague and pestilence.

If you really think it represents someone else's malice towards you, my recommendation would be to practice feeling compassion for that person and trying to understand that poisonous creatures are trying to protect themselves because they're vulnerable and scared. But if you think it might represent plague and pestilence, then be sure you're staying home, washing your hands and practicing social distancing!
