As someone who has suffered from insomnia for about 15 years now I know that unsolicited advice regarding the insomnia can be annoying, as you likely have tried just about everything, but I'll share my experience as my solution was a little unique. I was at a point where I would be awake for 3-4 days in a row without falling asleep at all and it was affecting my life in all the way you can imagine. I had tried many medications up to and including benzos and ambien (not recommended). One day I was listening to a podcast and learned about Cognitive Behavioral Therapy for Insomnia. CBT is a therapy method used for typical therapeutic practice, but CBT intended for insomnia is a newer technique. Seeing a sleep therapist is the one thing I had not tried though of course many people had suggested it to me. I liked what I heard on the podcast and found that there was a practitioner in my state (it isn't a very widespread practice yet).

I saw her monthly for about 8 months and it greatly improved my ability to fall asleep. It has been about two years now and while I still have trouble sleeping many nights, I at least fall asleep almost every night of the week and am probably getting about 6 hours on average. The most important things I gained from the experience were:

1. It turns out that much of the generic sleep hygeine you find from a simple google search on insomnia does make a world of difference when you actually apply all of it in a structured way and stick to it for months. Paying the money I was paying to see this therapist and having to keep a sleep diary that I showed her monthly made me really stick to the routines and I realized that I was only half assing a lot of this stuff before.

2. She worked with my sleep/wake times, regularly adjusting them by minutes or hours to get as close to we could to what my natural cycle might be. After the first month and a half I was getting drowsy by 9pm, something that never happened to me before. I never got the heavy eyes feeling of wanting to go to sleep like other people seem to. As soon as this started hitting me it was a profound revelation that I COULD have a normal sleep schedule again. This was a major mentality shift and a huge morale booster. After my first few nights of falling asleep naturally I knew that I could do it, it was proven. Once that barrier was broken through it was basically a matter of sticking to all of the routines and techniques I learned through the process.

3. Waking up at the exact same time every day is far more important than when you go to sleep (though this is also important). Once my wake time was decided upon I had to wake up at that time daily even I had only finally fallen asleep two hours before that time. I still stick to this.

I'd recomend it to anyone.
