Experiences with trazodone

I went through a really traumatic event a couple weeks ago and it has really stressed me out. Over the last 10 days I have been struggling with sleep. Last Tuesday I got a full night sleep which was great but ever since then which was 4 days ago, I get 1-2 hours of sleep a night and just toss and turn and I’m so anxious. I also take Ativan every night to help sleep and I’ve been doing that for years. My friend has some trazodone and he gave me some but I am TERRIFIED to try new medicine. I don’t want it to make me lose my mind or get anxious or have a panic attack or anything. What is everyone experience with it?
