Hello blonde
I'm sorry you're having a tough time of it atm. After so little sleep, and everything else on top, it feels like its the end of the world. I know. I've been there.
I would take a deep breath and ask your son exactly whats bothering him - if he can tell you... and sometimes, they can't. Its a start. If there is something you can fix, then start there.
Re the fact he hates being the only one awake, I'd make his regular bed time about 9, when you're around and awake.
Then I'd start to do a few of these things... get him in a warm bath and maybe chat to him about his day while he's in there, spritz lavender oil on his pillow, get him into drinking this <a class="break-all" href="//:www.celestialseasonings.com/products/sleepytime-teas/sleepytime" rel="nofollow" target="_blank">Sleepytime Tea, get him to make a list before he goes to sleep of anything thats bothering him, or that he needs to do the next day, ban ALL games, TV, phones etc for AT LEAST an hour before going upstairs, and no caffeine either.
Lastly, get him to imagine while in bed (and I did this while sitting in the room) that his brain is being cleared of all thoughts, I got DS to imagine a large brush, brushing out a 'space' in his head. The get him to envisage somewhere warm and comfortable where he can relax.
Obviously don't try all the above at once. Maybe you and your DS have a chat about what he'd be comfortable with.
I tell you all this from experience as my DS (nearly 16) has had similar issues. We're nearly there...!
Meanwhile, treat yourself gently, too.
