How to fix this vicious sleep imbalance?

I been having some sleep problems for sometime now. I found out somewhat recently that I have the following issues going on with me.

Insulin Resistance
Pre-Diabetes
Forward Head Posture
Some other issue with my spine due to terrible posture that's putting a lot of pressure on my throatic spine, causing my chest to feel like its caving in
Stage 1 Adrenal Fatigue
Midly Overweight (235 being 5'10 24yrs old, I weighted more in my life and had worse weight troubles over the years so this is not the worst thing IMO)

The Diabetes/Insulin issues seem like I'm taking care of them fairly well. I been on Paleo for 2 1/2 months now and I think Im doing ok in that department. I havent touched any garbage food since then and I do feel happy about how I been dealing with this. I lost some weight and I feel a little bit better mentally and physically. I wish I could be losing a bit more weight but once you read below why I been having trouble it would make sense.

The spine issues are slowly being worked on with a chiropractor. Im doing some theraphy with this biophysics thing called a denaroll, where its going to slowly fix my posture along with getting adjustments from the chiro. Sadly, he says this could take up to half a year, but I been progressing well with it so far so maybe shorter. My chiro doesnt want me going back to the gym yet, since he says my spine is pretty f***ed up and its going to take some good time to fix. I believe he is right since so far my spine is starting to have more increases in motion and things are slowly improving. Also luckily, I have no damage, just ugly posture thats temporary screwing me up.

My biggest issue with my life though however is how warped my sleep as gotten. Im stuck on this schedule to where Im passing out naturally around 8-9am in the morning and then awakening around 4-6pm. This is so terrible since Im literally watching my life skip through itself. I cant really break out of this awful pattern. What makes this worse is how I have to deal with the drama from my family all the time. Granite, its harmless crap, but its just small minded bullshit that I shouldnt be putting up with at 24 years old. That crap stresses me out a little but its more stressful that I cant sleep right so I can get a job, move the f*** out and not deal with this shit and move on with my life. I dont have much of a life because of this happening since my days are always starting when the rest of the world's day is ending. It sucks too since its winter and when I get up, its pretty f***ing cold and miserable compared to earlier in the day to where its still bad weather but at least manageable.

My chiro and integrative med doctor told me I have mild adrenal fatigue from testing they have done and while my integrative doc couldnt figure out, my chiro thinks due to my forward head posture putting 42 extra lbs on my body due to my neck shifting so far ahead. Well, I get that, but I dont get how I can realistically wait 6 months for it to get fixed and just deal with this abysmal sleep pattern until then.

What is anyones thoughts on this? I been jaming various sleep supplements like Valarian root, cortisol manager, etc. but they do nothing. Its pretty obvious that they do nothing, since my neck and back are putting so much stress on my central nervous system to where Im constantly in Flight/Fight mode, so a supplement cant really break that. Im just at a loss of what I can really do to help my situation.
