Welcome to the site.
Well yes lorazepam is known to unmask depression which on it's own can lead to self inflicting / self cutting thoughts and attempts but more importantly lorazepam directly can cause suicidal and self harm thoughts which many times involve self cutting attempts.
So I reckon that since there can be a relation between lorazepam and self harm so this drug can be taken off and then re-assessment of the self harm thoughts.
I hope this helps.
Wish you all the best.
