After the birth of my second child, I had postpartum depression and one of the biggest struggles was insomnia. For the first three months of his life, he slept like an angel while I obsessed, paced, and cried about not being able to sleep. I would start worrying about if I was going to be able to sleep at dinnertime, which kept the cycle going. My therapist gave me a few wonderful strategies to work through it. She suggested that on the nights that I was lying there wide awake, freaking out about not sleeping, I should accept that sleep might not come that night and replace it with a good book or a mindless tv show. Tell myself that the worst thing I would be in the morning was tired, that I wasn't going to die from missing some hours of sleep here and there. She also recommended meditation to get my body into a relaxed state, so that even if my mind wasn't resting, my body was. It took a few weeks, but it slowly started to help, and I found myself falling asleep for a few hours while reading or watching tv. I hope you find something that works for you!
