How to supress anterior pituitary gland from secreting ACTH?

[Barbarossa]

I know that Benzodiazepines acting like ACTH and anterior pituitary hormone blocker, but What are some alternatives for Benzos?

I have high ACTH 177 (4,7-48,8) due to a pit tumor!
With a Benzo (Lorazepam 0,5-1mg) I feel much much better within hours.

I can go out and be a social person and can live like a relative normal person.
