Anxiety-induced insomnia is not normal. It means your anxiety is being caused by something that is keeping you awake and unable to sleep. It could be a health problem mimicking anxiety. Ask your general practitioner for a referral to see a cognitive sleep specialist. Or, if you have to pay out of pocket do it. A sleep doctor knows more about this than any psychiatrist or general practitioner.

Try keeping an anxiety journal to write down everything you are worried about as part of your bed time routine. If that doesn't work, then schedule your worry. Sounds silly. But I do it and it works for me. I schedule 15-20 minutes a day where I allow myself to get really worked up and overreact about my problems. Then, I force myself to stop worrying after that allotted time is up and I reframe my worry after that as problem solving. It's all about reframing.

I have 4 months of savings to find a job. I could keep myself awake every night in a tizzy worrying about finding a job right now with COVID. But I refuse to let it control me. So, I set aside time every day now, to worry about finding a job and let myself get really upset about it. Then afterward, I go into problem-solver mode. I attend online job fairs, get online help with my resume, and continue to apply for jobs.

I had 3 sleep studies done because I had anxiety keeping me up at night. Turns out, it was a combination of factors; mild sleep apnea can mimc anxiety, segmented sleep pattern (I've been this way my whole life), and low in iron, B, and D and magnesium. Also, my sleeping environments at those times were uncomfortable; dry, too stuffy/humid, too noisy. All of that can effect sleep.
