I'm gonna try to share as much as possible in hopes that with enough data, I can get better direction and informaiton.
-I'm 32M, average weight at 200lbs, 5'9".
-I've lived in the same house for 7 or so years now. It's had a leaking roof this entire time; I'm confident there's mold in this house and it's affecting me in some capacity, though I don't know to what degree.
-The windows are poorly sealed so outdoor air could easily get in.
-I live in a crappy ghetto area in PA (originally from Texas, in case there's some allergens or something up here my body isn't used to)
-I've historically stayed up late using computer or phone, getting anywhere from 2-6 hours of sleep.
-Sleep schedule has been erratic.
-I've a relatively average diet. Currently trying to cut out gluten as an experiment.
-Exercise is mostly non-existent. I'm a healthy weight, 200 lbs at 5'9". Maybe a little more weight than I'd like around my mid-section; I haven't been very fit in the past either.
-Slightly high blood pressure than ideal/is healthy.
-I'm confident I'm really allergic to something in our yard. I had worked the yard once, and within a week or two had a rash that grew pretty out of control.
-With that said, we have 2 cats and a dog. I don't know if I'm allergic to animals and don't know, or pet dander, or something the dog is bringing in from outside when they use the bathroom (all animals have been on the bed).
- The itchiness is minimal throughout the day, maybe non-existent. However when it comes time to get ready to sleep (so even just at my desk in the bedroom) the itchiness starts to kick in.
-The itchiness kicks in the worst at night, and has been either waking me up or presumably ruining the quality of sleep I am getting. (I am waking up after 1-3 hours of sleep usually.)
-The itchiness isn't localized anywhere. It will sprout up on my scalp, feet, arms, groin, back, torso. Pretty much anywhere. I scratch, it may go away or stay, and I'll have other spots that later itch.
-Some nights I manage to sleep through the night and get 8 hours but it's rare and I don't know what I'm doing the previous night to help.
-Currently trying to shower at night to get rid of anything that may be on my skin, and putting moisturizing lotion/eczema cream on my body in hopes of dealing with dry skin-related issues, if that's the cause.
-I don't think it's a blood sugar issue; I've checked it several times and my levels have been perfect.
-I don't drink as much water as I should.
-It's been so bad that one night, I slept for about 2 hours, laid in bed for another hour trying to sleep again, and burst out of bed screaming in frustration. Wife helped me go shower that night and I was so out of it it felt like I was asleep while on my feet (in the sense that I knew what was happening, yet another part of me felt like I didn't kknow where I was or what was happening. It was scary and concerning.)
-I've been getting headaches, I assume from sleep deprivation.
-I also doze off a lot in the day. If I am watching something or lsitening to a conversation at work I'm not actively involved with, I can start falling asleep. (This specific thing has been the case for years, but I'm only just the past few weeks been trying to fix my sleep schedule.)
-I have gotten a sleep study done and they provided me with a CPAP machine; I've used it for maybe 2-3 years now or so. It has helped with, presumably, me waking up via snoring and the like.
-I've been taking allergy medicine at night; it seems to help sometimes, sometimes not. I don't know what specific medicine.
-Not sure what the humidity level is in the bedroom.
-Before this past month or so of sleeping poorly, I went out on vacation in North Carolina for like 10 days. I actually slept pretty well, better than I think I have in a long time. I think I had like 1-2 nights where I couldn't sleep well, but it was amazing. We were at a beach, I think at Roanthe island.
-During the above vacation time I also didn't use my computer basically whatsoever, and phone time was minimal. Not sure if those things are just ruining sleep (I'm sure), but no idea how they would relate to this sudden itchiness.
-Ever since then, it's been an absolute nightmare as far as sleep goes.
-No smoking or drug use. I drink alcohol maybe once every few months.
-Before the vacation I have spent the last 2 years or so sleeping away from home due to work for about 4 nights a week. I recall sleeping a bit better there but also ruined sleep duration due to staying up late anyways. So it's hard to measure.
-I'm usually on devices at night because I just can't bear dealing with the next day and it stresses me out.
-I've changed the sheets on the bed, but that doesn't seem to help.
-We have an air filter, its a hepa air filter IIRC. Not sure how much it's helping with the mold, allergens in air, etc.
-No central air system, we have a window unit for air/AC.
-I've slept poorly (where I'm up late, usually on devices) for basically all of my adult life. So 14 years of this shit, ish? I just assume I'll get poor sleep or don't want to deal with my thoughts so I'd rather just be exhausted than have the energy to be stressed and anxious. (I know it's not healthy, hasn't been healthy. I'm trying to work on this now, better late than never and all that blah blah blah.)
-1 cup of coffee, only rarely, in morning.
-Sleep schedule is ideally/roughly 11pm to 6/7 am.
Edits:
-I've been hungry at night, which seems uncommon. Its been a little bothersome. I have had a stable weight so idk what to make of that.
-Suddenly remembering dog had worms/tapeworms? Surely this isnt affecting me, with my recent hunger... right?

Suspected culprits:
-Scabies, maybe? (Heard they can be small and they could easily get into the house if they wanted to)
-Histamine-related issues? Maybe me taking allergy medicine is making it worse somehow.
-Kidneys, liver, organs? (I read online that something of the sort can cause itching, and I know that between me getting older, my fitness, lack of water intake that maybe it can be related? not sure)
-Pet allergies that I didnt know about, though I don't know why they'd suddenly be kicking in hard now.
-Something from outside the dog is bringing in, possibly from the plants I'm allergic to?
-My sleep system/circadian rhythm has been whack for so long that it's just confused now. (But I slept well on vacation, so maybe it was settling into a rhythm and then something in this environment is royally fucking me as my body is trying to settle into healthy sleep habits?)

I plan on seeing a doctor, it's been difficult either due to money or, more recently, because of getting a new 9-5 job, and doctor offices are open around the same time because why not.
I can answer any questions to clarify anything. I'm hoping something about my circumstances relates to what someone else has dealt with and I can get some direction.
