Night shifts with insomnia

Hey fellow insomniacs! I need your take on night shifts. I will have to start working night shifts (on monthly basis, or bi-weekly) and at the moment ai cannot change the circumstances.

I have isnomnia for years but lately I manage to sleep around 5-6 hours which is fine. I usually cannot sleep properly after 7am or throughout the day, as light and every single sound are interrupting my sleep.

Any tips on how to manage that I am scared to go to bed at 6-7am as I know I will hear the birds, the traffic, the kids going to school etc.

My insomnia is mostly induced by anxiety and the fear of not sleeping, so it makes it worse.
