Are you withdrawing on your own or with medical support? There are some Rx options that can make it easier to phase out benzoes.
While Quetiapine has its very own risk/benefit profile it can be helpful to curb anxiety on a very low dose (but it also makes you really groggy).
You may also want to try CBD/edibles to make the transition easier.
Coming off Lorazepam for me was ROUGH. Headache, nausea, exhaustion for about a week. I had been on it longterm but low dose. First taper down to lowest possible benzoe dose and substitute if needed with Quetiapine (at night, to avoid being tired all day) and/or CBD edibles.
To be honest: if you have debilitating anxiety you may not be able to go without meds completely. You may not be able to return to work, especially not shift work, until you have a stable, consistent medication and sleep schedule.
