I strongly believe that the best thing CJ can do right now is simply work on stabilizing. While some sort of inpatient program would be ideal for this, the practicality of finding one in America that will allow you to take methadone, or even a maintenance regiment of buprenorphine (one of which I think CJ is far better stabilizing on than trying to get off ORT at this point of extreme instability), and take a regular doses of potent gabaergics like a benzodiazepine is very, very difficult (if not impossible 99% of the time).
There is a really great buprenorphine specialist I can get the name of for you CJ, who I am sure would be able to find you something along the lines of a facility that would at least allow you to continue on benzos and buprenorphine. Please let me know.
I think a big part of stabilizing is going to be finding ways to stay away from your connect and using friends. Anyone who's company leads you to binge on IV coke and research chems is just going to lead you further and further away from your goals. They cannot help you, and now that you have a benzo script again there is no reason to remain in contact with them - short of falling back into a place where you're living just to use of course. That would be the only use of remaining in contact with them, to use them to get high (and in turn be used by them for their own selfish, no matter how well intentioned, ends).
Have you considered increasing your methadone dose? That could help you stabilize, as well as helping with cravings for benzos. What dose are you taking these days? Remember that there is no ideal dose, it is always individual. There are people I have met who, god only knows how, remain function on doses over 300mg. I am not suggesting any particular number for you mind you, just making the point that you shouldn't limit yourself to remaining at the current dose just because you think it is too high if it leaves you craving other substances.
I'd seriously consider thinking about increasing your dose ASAP, while you have a steady and reliable supply of benzos (even if it isn't as high as you like perhaps, it is far better than nothing as you well know). Remember that tolerance to gabapentin build very rapidly, so enjoy it while it lasts (considering you are already tolerant to benzos I honestly don't know how well it will work for you, but it should help reduce your cravings).
Along those lines, have you ever taken baclofen? It is used to treat alcohol use disorder and dependency, and works quite well IME to curb cravings for gabaergic substances. It will also fuck you up like you probably want, without being as dangerous as continuing to binge on various other gabaergics like the benzos. If they're willing to prescribe you clonazepam, I highly doubt they'd have a problem doing so with baclofen. Mind you, the withdrawal is super shitty, but it is a lot easier to taper with than a benzo.
Whatever you do, I highly encourage you to think about increasing your methadone dose, if only for a few months until you're feeling more stable.
Have you considered some kind of healthy extracurricular activity, like yoga for instance? It would be an easy way to get you out of the house and give you something very healthy to do, and is more accessible in your part of the country than the MBSR stuff I'm into (it would be worth research if you can find an MBSR course in your area, as this would be even better).
Though, realistically, full time school isn't the best idea right now given how unstable you have been recently, I still think pursuing healthy activities involving learning, but only subjects you are generally interested in, would be a very, very positive step for you to take. Are there any local community college you might be interest in finding a class or two to take at? The workload at a junior college is pretty minimal (it is essentially the same as high school, just with more interesting subjects).
I think you should keep in mind that, god forbid, if you have another episode while taking a class you can always easily get medical leave so a leave of absence won't affect your grades or anything. Plus you can always start with just one entry level class, there is no need to start with a large class load.
Perhaps most importantly, I saw your earlier post about how you felt you let you fellow BLer supporter down in your most recent "adventures." Fuck no dude! You're still here, plugging away. If anything, going through what you have, and coming out of it as you have, deserves NOTHING BUT PRAISE and celebration. The only way you could let us down, shit, I don't even know. Maybe offing your parents
Keep your head up my friend. You have nothing to be ashamed of, just a lot of wonderful shit to look forward to as you extricate yourself from this very dark place you've found yourself in over the last year or so of escalating stress and problematic patterns of substance use.
Take your time, because it is also true you have a lot of hard work ahead of you. Stabilize itself with be a huge accomplishment, and that is only the beginning. But it is also, as you probably imagine - even if you might not be able to actually visualize the sense of accomplishment of submitting your mountain of guilt and shamed at your (merely perceived) failure - it is all more than worth it.
Stabilizing will not be easy, but more than ever it is possible. Increase the methadone. Encourage your mom to continue helping you managing your meds (frustrating though it is, this is more crucial than you might imagine; she might be annoyed as fuck with you somethimes, but as you get more stable your progress with be its own reward for her). Find something healthy you can do and master outside the house and world of drug use, whether something like yoga, MBSR, art, learning an instrument, school, use you imagination! You're smart and more capable than you know dude! Anyone can make it this long shooting psychosis enducing amounts of coke and eating huge amounts of benzos is far more capable than most at survival.
I also suggest you save up the money you've been using to buy you drugs with for some great adventure you are able to take once you get stable (I know you're not working, so I know it must be precious; do you have to do anything particularly distasteful (such as less than legal stuff) to get what you've needed to purchase drugs? If not then save it up!).
Even if it isn't moving to a new place (as methadone makes this very difficult, though not impossible), you can go on a vacation to visit a friend (you have lots of us you know) for a week or two would almost certainly be just the breath of fresh air the doctor ordered. We all need things to look forward to, especially we find ourselves in a place as dark as that you are in right now.
