if you want it, Ricky2020?
Is there anything you could try that it so out there that you've always wanted to try but have never got around to it? Or a magasine you can read in bed? Or a relaxing (nothing that gets your brain working, so no studying or new or anything like that) book? Short stories and gentle articles are the way to go... something to signal to your brain that it needs to shut up and calm down now kinda thing? How about exercising so that your body kinda goes "enough already!" when you crawl into bed at night? It doesn't have to cost anything, just walking a dog a couple of times a day then squats, planks, sit-ups and leg raises are what I do every day and I'm usually asleep in under 15 minutes every night now!
I walk our dog for about 45 minutes in the morning to get me going for the day, then another 15-20 minutes at about 4pm. I try and remember to do my squats as soon as I get back in the morning then come online all day, take my pills at about 7pm, head to bed at about 9pm, finish off the day with the planks, sit-ups and leg raises then read a relaxing magasine or book with my favourite radio staion on in the background, until I can barely keep my eyes open and the next thing I know is that it's 5am and time for me to get up to start my day again.
I know and understand only too well how much depression drains your motivation to exercise and it's the last thing you want to hear, but if you can find the motivation every day for a couple of weeks, hopefully you'll start finding that you're getting to sleep earlier and sleeping better too.
I've been where you are now and I've come out of the other side of it, so I'm just suggesting things that have worked for me is all
