Hypothetically speaking, would you prescribe a one off prescription in this circumstance?

The anniversary of my rape is approaching and I’m already suffering with insomnia and anxiety surrounding it. I have nightmares. I’m concerned I may do something stupid if I’m spiralling all night. It would not be the first time that I’ve attempted. I know already I won’t sleep a wink and would ideally like to be knocked out for the night. I’m curious if you’d prescribe a sleeping pill to a patient under this circumstance? I was wanting to get a general gauge on this before asking my gp. She expressed to me already she didn’t want to prescribe sleeping pills when I first went to her, as it’s just putting a band aid on the issue rather than addressing it properly. Any input would be greatly appreciated.
