You're obviously getting a lot of different kinds of advice, from "order more than pizza" to "300mg of gabapentin".
All of this advice is valid, and worth considering. But obviously comes from opposite ends of the spectrum.
I'd suggest starting with the type of advice
@ajc is offering, and see how far that can get you. As they said: you're likely in the panic stage right now - which, while totally understandable, is also almost always temporary. It *will* get more tolerable. You *will* learn to live with it. And I don't mean that from a "you'll find a way to survive" perspective. I literally mean: you will learn to live with it, and you will be okay.
First thing to do, as
@slc implied, is to find ways to make the sounds more tolerable now. Ocean sounds, white/pink noise, falling rain sounds, light jazz...whatever works for you: play it at just barely under the tinnitus volume, and learn that you can function that way, that you can get control of this thing. Play it during the day, play it while you fall asleep. It helps; a lot.
You should also find ways to relax. Consider meditation. Practice focusing on other sounds in the environment (not ignoring the tinnitus but steeling your attention on other sounds). Take baths. Put your head underwater, and steel your attention on the low frequency sound waves under there. Learn what takes the edge off the sounds - something always does, you just need to experiment.
Then you have to start picking yourself back up, and making good decisions for yourself. Yes, it sucks that there is no one there to help you...but you can do this on your own. As
@ajc said, start eating better. Force yourself to get out of the house. Go for walks (with ocean sounds playing LOW on your headphones). Find your inner strength, and make a decision that tinnitus isn't going to control you.
If you have to see a psychologist, there is no shame in that. CBT can be *very* helpful, for learning to switch attention away from the tinnitus, and also for finding ways to cope better even when you can't.
Then - only then, once you've tried all these things - should you go the psychiatrist/medication route. Though, obviously, if you need to, there's no shame there either. But it's so much better if you can come to terms with it on your own.
And then remember that you're not alone. You have a whole community here who are always happy to lend and ear, offer some advice. Hit us up whenever you need. We all understand (approximately) what you're going through. And we can all tell you that it will get better...
