In need of support. Has anyone struggled with insomnia here? I'm floundering

My anxiety is so bad. Two weeks ago my body forgot how to sleep. I slept fine before then. Its like I get so close to sleep then I can't. Some nights I've only gotten an hour of sleep.

I went to the doctor a week ago and started zoloft and got the sleep pill zoplicone. The zoloft is making my anxiety so much worse. The zoplicone helped me sleep for four nights. I was still waking up every 1-3 hours, but at least I was falling asleep easily. Last night, suddenly, it didn't work anymore. I slept for 2 hours and was up the rest of the night. I'm devastated today

I don't know what to do. My doctor is out of town until March now. My anxiety is horrible. I feel so hopeless and like I'll never feel better and never sleep properly again. Laying in bed with your eyes closed for hours but not sleeping is a certain kind of torture. I genuinely don't see the light at the end of the tunnel. Can anyone share advice or commiserating or success stories? I need all the help I can get
