There are sedating antidepressants that help with the depression and help you sleep better. Trazadone is an old, tried and true drug that serves both purposes. It is being prescribed for sleep instead of the controlled drugs by Drs who don’t want to deal with controlled, traditional sleeping pills. It’s not addictive. It does sometimes take a couple of hours to kick in so have to get used to taking it earlier. It might be worth a try. I hope you find the right one that relieves the insomnia and depression both.
