I have tinnitus too since a long time ago. I don't know how to assure you, so least I could do is tell you how I've been "debugging" it.

1. Idle Background Music There's a 1 hour white noise music on Youtube with all caps "MOST POWERFUL TINNITUS THERAPY" etc etc or something (been years since I saved it on my phone), it has beeping sounds mixed in. I open that on speaker when I'm alone or using earphones when I'm idle outside. Use it with volume slightly louder than your tinnitus level, and volume down when the tinnitus end gets quieter, match it like tango. It does get quieter, but it'll come back. I don't really bother with the volume down thingy since it stills helps reduce and contain the noise (lazy debugging). In my case I just simply can't not have any sound at all or the noise takes over and escalate in loudness. Long trips are especially hell, so fill up your playlists from the get go.

Hearing aids cost a lot so this is my workaround. Phones are handy these days. Why not. Though, if you can get a hand on hearing aids, think and go for it.

1. Take care what you eat Certain substances makes the sound louder through science magic (not an expert), and for me they're salt stuff like instant noodles and caffeine in coffee. I've sworn off them but tea is nice to have once in a while. Treat yourself but not too much. You have to see for yourself what's good or bad.

2. The back of head hand whipping thingy another redditor posted in comments It's a blessing because it really does erases the noise, but only momentarily. I get tired doing that, so save it up for when the noise gets too frickin' unbearable - and find a private room to do it lol people look at you weird when you just casually whip the back of your head multiple times.

3. "Distract yourself, focus on life" Tinnitus therapy sucks balls cause my wack doctor thinks I deserve it for not being devoted enough to god. You're supposed to see the doc once a year (with goverment hospital they have to identify that you have tinnitus where I'm from) but I don't bother with him cause he can't even tell the cause of mine's. (When you get your doc, love em' for me.) That advice of his works though. Sometimes I forget that I have tinnitus (which is a disaster when I get into near-soundproof rooms like big halls, they make tinnitus louder), bad advice but you get used to it. In that time, do what you like, talk to people you like (or text; phone calls is like talking with gramma with me) don't let all that time go because of tinnitus. You're six months in the tinnitus club, you gotta play with it now. I don't personally know you, but you said you had a career, and your old life was nice but now it sucks balls like that wack doc. You can still have it. It will never be the same, but you decide whether you can do it or not. Don't give in to the noise, it gets louder. Good luck.
