When I lie down to sleep, I feel like I'm going crazy. Insomnia is so hard.

I'm having a hard time sleeping at night these days.
When I lie down in bed, my mind becomes fuzzy and my thoughts only increase.
Even though I'm tired and lie down, I have trouble falling asleep, so I just spend time lying down and my condition is terrible the next day.
My insomnia has been getting worse for a week now, and I'm worried about how I can sleep comfortably.
