I am so sorry for your loss. It’s little wonder that your sleep has been suffering as a result of you losing your husband. Fortunately, there are many steps you can take to improve your sleep and prevent your insomnia from becoming more entrenched.
Can you tell me a bit more about your sleep so I may offer a few suggestions? When do you normally go to bed, when do you normally get out of bed, and roughly how many hours of sleep do you get each night at the current time?
