Help

I’ve been having insomnia flairups recently and don’t know what to do. Today is day 3 of crap sleep (no more than maybe 5.5 hours if I’m lucky) and that’s with medication. It’s either that I can’t fall asleep or that I can’t stay asleep. I know worrying isn’t helping but I don’t know how to get it off my mind, especially when I’m lying there exhausted and not sleeping. I’ve tried everything from mindful breathing to counting backwards from 399 in threes, and I get impatient and wonder why I’m not asleep yet. I’ve been recovering from covid last week and this sleeplessness is making everything worse but I’m out of sick days to use this year. I mentioned it to my therapist and she wants me to try trazodone but I feel like there’s gotta be another way. What do I do?
