I don't know if your tinnitus is louder than mine; I can hear mine over nearly-but-not-quite-everything that I'm exposed to in the world. It's shrill, and the parts of it that are super high pitched (around 14.5khz) are very unpleasant sounds to me. That said -- not only do I sleep okay, I sleep with earplugs most of the time (the wife snores, the cat meows, the kid screams) --
and you can learn how to do that, too.
Again -- you are not broken. Your mind isn't broken. Your body is keeping you awake because you are in a state of fear/hyperarousal, so you have convinced your limbic system that there is a
threat, and as long as you are threatened, your nervous system says "OH NO I AM IN DANGER I NEED TO RELEASE LOTS OF ADRENALINE TO STAY ALERT".
It's basically impossible to get real, useful sleep in that situation. Yeah, you can carpet bomb your GABA receptors with Ambien or Valium or something, and that will make you "sleep", but it's not good restorative sleep, and over time, those drugs are gonna cause you worse problems than you have now (unless you only take them ~once a month or something, which is probably fine -- I still take the odd valium when I am unable to distract myself from T or other anxiety.... but a bottle of 30 pills lasts me 2 years).
What you need to do, is convince your limbic system to shut off. That you are not in danger. That you are safe and loved.
It sounds cheesy as hell, but when I was at my worst, I would lay in bed all night, just telling myself over and over again, "I am safe, I am loved". I would think about how safe and secure my body was in a comfy bed. I would think of all the people and animals that love me and wish me well.
If you can get to a place where you are able to lie in bed, sleepless, but
not anxious, not
afraid of being sleepless -- you will be well on your way to getting out of this. And, if your T is anything like mine, it gets louder, nastier, more obnoxious, the less sleep you are getting. So, when you reverse that, you will still have tinnitus... but it might be a very different experience than what you're dealing with now.
As to
how you snap out of that, sorry, I have no magic. For me, I basically had to find a unicorn: an MD psychiatrist who thinks drugs are scary and dangerous and should be avoided. He just reminded me over and over that actually insomnia was not going to ruin my life. I would call him frantically at 7am, swearing that if I had another sleepless night I was going to lose my mind, begging for valium... and he'd just say "no, you're fine, drugs might make a bad situation worse, and actually you're fine, really, even if you don't seem to be sleeping, if you can lay in bed as calmly as possible you are getting rest even if it doesn't feels like it, trust your body". Blah, blah, blah. Somehow, over a period of time, between making those frantic phone calls, and being pretty dedicated about exercise, meditation, and sleep hygiene... it all went away.
Now I have a screaming baby in the house who doesn't give a rat's ass about my sleep needs, a demanding period at work, and a wife who is also not sleeping much because of the baby... so, my sleep lately again, is quite a mess! But, something fundamental has changed in me, because now when I don't sleep I just think "huh I'm not sleeping, I'm gonna be tired tomorrow, that's kind of a bummer", and totally don't get anxious at all about it. That took me years to figure out, but I'm not particularly clever or resourceful, so if you are a clever and resourceful person you may be able to turn this around a lot faster than I did. Also, I was horribly addicted to sleeping pills at the beginning of this nightmare, which probably made it a lot harder (and that's why I'm skeptical of ambien for people with severe anxiety-based insomnia).
Anyway, sorry to leave you a wall of text, but hopefully some of it is useful. I have a laundry list of free resources that helped me (guided meditations, stuff to read, exercise protocols, etc). Happy to share all of that. Basically, my tinnitus is a pain in the butt, but my tinnitus combined with severe insomnia was an entirely different level of hell and I hope to avoid it....
edit: one FINAL caveat -- if you're so strung out now that you just need to get. some. sleep, come hell or high water -- I don't personally think it would be very risky to take ambien for a couple nights to just get some sleep and catch up, and have fresh eyes and be a little more balanced about this whole thing. But, every time you resort to ambien, you are teaching yourself "I am broken and can't sleep without drugs", and that is a very hard lesson to unlearn, so I would say try not to do that unless you're on the verge of completely losing your mind. Also it's a weird drug and can sometimes cause hallucinations (not the fun kind), and there are documented vestibular effects (so it could potentially interact with or worsen tinnitus, as with all the BDZ-like drugs).
