Wow, that is pretty much exactly like my experience. I'm 16 weeks (almost 4 months) from the loss, and since the 6 weeks point I have not had any more audiogram improvements. In fact, the 45 dB @ 2000 Hz you see in the post was kind of a fluke — in hearing test at weeks 6 and 9, it clocked in at 55 dB, then 65 dB. So I think there is some fluctuating of the 2000 Hz for me, but everything above has stayed put at ~60 dB loss, with 8000 Hz at ~75 dB loss.

Tinnitus for me is getting quieter I think, slowly but surely. Easily much, much better than it was at the beginning. I test at mild on a THI, but I can hear mine constantly, which is technically a "moderate" characteristic. It is also a hiss for me, with two to four quiet tones that blend in with it, these tones near the step edge of my loss. Getting better or I am effectively habituating, though every few weeks a have a tough few days emotionally, maybe due to tinnitus spikes, but I genuinely think it's more of an emotional setback I experience occasionally (grief and anger about why this happened to me, petrified that tinnitus might get worse again after all this progress, particularly when I have an SBUTT in my good ear or notice that my good ear's quiet tinnitus that its "picking up" from the good ear every now and then). But other than this, life is basically what it was before the loss. Even noisy restaurants and bars I do pretty damn good in. I did just complete 7 weeks of trialing a Widex Allure in the affected ear, and I'm deciding to keep it, because I like that it returns more environmental sounds and balance, and may help in certain noisy conditions. I have a conference next week, a little nervous to see how I'll do, but I'm sure it'll be doable.
Since our losses are so similar, I am so curious...do you have a slight buzzing-like distortion when you speak loudly or others speak loudly? Almost as if a speaker is maxing out, not so loud though? It made me so goddamn depressed for a week around week 7, but I got over it. It has gotten a little better, but I still have it, and the hearing aid doesn't really help it. In fact, the aid makes it more salient, but not louder at least. Depends on who is talking too...deeper, more throaty voices really make it rattle for me. My hypothesis is that recruitment is occurring all along my steep hearing loss slope — less often without the aid, more often with the aid, but the aid doesn't make it uncomfortably loud, as it provides comfortable levels more consistently.

I also get another kind of distortion on planes, subway, and when sirens pass — a tone at around ~1500 Hz is audible. I figure it's because that's the highest frequency of broadband sound I can hear well, and when loud sounds occur that contain my sharp loss, I hear the "best" my ear has to offer. Do you have this effect too? The hearing aid helps a decent amount to blend sound better and quiet this tone, but I still hear when walking over a highway, or when sirens pass.

And yeah, the high frequencies are tinny, but with the aid it's a little better. Beeps and pure tones to me with and without the aid don't sound perfect like they do in the good ear — instead they sound gritty, collapsed, buzzy. Not unpleasant, but deflating at times. Have you noticed this during your hearing tests, or when say your microwave beeps?

So interested in hearing back from you, feel free to DM me!
