Sertraline + Lorazepam

Hi everyone,
I’m on day 12 of my treatment for depression and anxiety. I have 50 mg of sertraline and 1mg of Lorazepam (which I was supposed to take three times a day but had to cut to 2) which is making me sleep all day. If I take only half though, I get really agitated and I suppose that comes from Sertraline. I’d like to stop benzos altogether because they just make me sleep all the time. Has anyone done this before ?
Thanks
