I hope it saves your life, sleep is fundamental for a good living. Insomnia is truly hell and I've considered roping because of it. Now I take meds to sleep, and it works, sometimes not, but when it works, I can sleep a lot, absolutely monster oversleepings, but it's better than staying awake for 2 days bored to death, feeling tired and sleepy but unable to actually fall asleep. Even though I've been severely depressed for many years, being able to actually sleep occasionally has greatly improved some of my days, and sometimes I wake up feeling energetic, which is very uplifting.
Exercising is a great way to force energy as well even if you are tired, there will come a point where you will feel very energetic and really get up with it, talking by experience. Can't guarantee it's gonna happen but when I tried, it really helped me. I used to walk multiple kilometers a day right at the sunrise and then around 12:00. It was really good. I would die after the first sessions in the morning, but when it become a routine I felt I could walk for 10 hours non stop and not get tired. My legs got really strong and my mood improved overall, as well as sleeping. If you live close to nature, it can be a real relief walking by the woods, river, lake or sea. If you live in the city, go to the largest park you can find and just walk all over it until you need to rest. If it feels uncomfortable, just pick the time when there's less people, like very early in the morning with the sun rising, generally at the start of the nautical twilight. When the sun rises, you can go back to home or just stay in the sun a bit. Early morning sun is such a chilling, beautiful experience. I can't count how many times I was outside alone seeing the sun rising and stayed there abit after the sun rose to feel a bit of it, and would come back later to get a bit of smooth heat when it was just comfortable enough instead of an oven. It's a real pleasure when you really feel like doing it and get habituated to it.
Now, years later, I've just been LDARing to death because I can't do any of it anymore, I just... don't have the soul anymore, or energy or motivation. I tried to exercise at the start of this, tried every day multiple times a day, until I gave up, but when I was exercising regularly I really felt an improvement in energy. You should try. Your first priority should be yourself and yourself only, put yourself above everything and everyone for your own well-being. When you feel good enough, you will have the energy to do a ton of stuff, better mood and motivation. Don't forget, having energy can make you go really far. That is, if you can get to that point before giving up like me.
