I’ll give you help, Sha. I am a grammar psychic.

It should be “If you are a true psychic” or “If you’re a true psychic.” “Your” is possessive, like “Your psychic power is grammar.”

My apologies. My power is a curse! I can’t help it! My psychic grammar power flows through me like lightning. I only want to help humanity defeat the evil of incorrect grammar.

Thank you for your understanding. I hope this helps.
