Struggling to Get a Good Night's Sleep

Hi, I'm familiar with the problem since I had something similar. For me it happened after a very big loss in the family, I was constantly busy thinking about the loss, I couldn't fall asleep at night and I was unable to function afterward during the day with work and children. The thing that helped me the most is divided into two. First of all, create a "clean" sleeping environment, meaning not watching TV, not playing with your cellphone, simply getting into bed, turning off the light and going to sleep, In addition to taking a sleeping pill. The pill helped me overcome the "fear" of not falling asleep and after a few weeks with it, I was able to fall asleep even without it. What do you think? Have you tried it?
