You might want to try mindfulness as a strategy to at least deal with an excited mind. I use the Headspace app and there’s a fee. It has midnight SOS meditations. I haven’t had insomnia since I’ve been medicated with antidepressants for the last 10+ years, so I haven’t needed it for sleeping. But, I love listening to the silly bedtime stories at bedtime and the odd times when I do wake up at night and can’t get back to sleep. It does a good job of switching my big old brain off, which feels very relaxing. You can also take a look at this website. They seem to have a ton of material. https://www.mindful.org/a-mindfulness-practice-for-better-sleep/ Good luck. Insomnia was my precursor to deep depression. Praying that you find relief.
