Workings #77943 Can I do a Mars square to reduce its negative effects in my natal chart? And affirmation?

[AskSatanOperator]

I have terrible Mars placements and it can give me terminal diseases.

Can I do a Mars square and affirm something like "This energy is healing my natal Mars in positive and healthy way for me."

Or can you please suggest me another good affirmation?

Thanks for answers.
