Abstract, I'm so sorry! But I do understand. Been in a similar situation myself.
StrongerNow, I'm sorry if I went into a long list of things, and none of that really helped. I know, I know. {{Hugs}} I threw it out there because I often forget about the things that have worked in the past, and I need reminding. But really, the sleep problems, that's the PTSD. Sometimes it helps to have a list of things to try, and just trying some things takes your mind off the real reasons you can't get to sleep. Sometimes. And that's where I was coming from with that.
But truly, you have so many stresses in your life, you're suffering from PTSD... so, well, given that... your sleep schedule is kinda, well... normal, give the circumstances. Maybe "to be expected" is the better way to phrase that, okay?
I've kinda given up trying to have a normal sleep schedule. I just go with the flow. Whatever is happening, fine. I put zero pressure on myself to sleep (mostly) and only lay down when I'm seriously sleepy. Yes, this leads to a terribly mixed up sleep schedule. But I just... I couldn't spend all my energy fighting to be like a normal person anymore. So, I just accepted... this is what it is. And I adapted. I do all kinds of things so that everything keeps moving along even if my sleep schedule is off. I make meals in advance and freeze them. I have 16,000 color coded to do lists and charts that my family refers to, so, if I'm not around to nag (because I'm sleeping), they get that nagging for free, online, in Google Docs I've setup to keep us organized. ;)
Sometimes, it's all that fighting against everything that's going wrong that's the worst part. Just accept... you suffered from a trauma, and your sleep is going to be messed up, and do the best you can. I'm like you... if there's something important, I can always, always get up and moving. But when there's free time... well, then, I am TRYING (not good at this at all, but...) to just say, fine, that's me time and if what I want to do is sleep, then sleep it is. So... maybe what I'm saying is something along the lines of... maybe try to stop fighting against the way PTSD and stress has changed your life, and accept it for what it is... your body is disregulated, it's stressed, and your general needs are different.
Anyways... the main point I wanted to get across, is that, I think we ALL struggle with sleep. A LOT. You are not alone. And maybe, as fellow sufferers, we all went to the... "56 Tips to Improve Your Sleep!" mode, instead of just being understanding. But we're all very understanding, as well, I think. We all struggle with this. Most important thing, don't be too upset about it, if you can, which is hard. But let yourself be understanding to yourself, y'know? You're having trouble sleeping, but that's totally understandable... so many stresses in your life (so sorry!) and you need to just take care of yourself in whichever way makes you feel better. Don't lie in bed beating yourself up (figuratively) because you can't sleep.
Anywho... I hope any of this helps. Sleep problems just.... SUCK! ;)
Hang in there,
Everything changes,
