If you genuinely want get it sorted, have a look at the recent stuff on here about dealing with precipitous/ski-slope losses and the trade-offs you make with open and occluded fits.
I would absolutely look into getting hearing aids with a tinnitus feature. buyhear.com seems to be popular amongst the DIYers, so I'd look over there. I also have tinnitus, and I find that when it gets bad, there's no stopping it. Next time I get HAs I will also be looking for that feature. Oticon, Widex, are two that family members of mine wear, and they swear by them. Also, when you get a hearing test, ask if they can change the tones according to your tinnitus. I don't remember what it's called, but they can do something so that they get a better reading of your hearing.
If you have aids that can stream, all the app stores have a variety of tinnitus apps. You can try them to see what works.

You need to get a proper audiology test done. Find a good audiologist in your area and go from that appointment. When I was trying HA's I tried Oticons and didn't like them. So I tried some other brands, just because someone tries to sell you a particular brand ask to try several brands as they all differ slightly. If the audiologist you choose won't let you do this do a ring around and find one that does. Good luck ..
I also feel that challenging as your hearing loss may be to fit (steep drop-off), there should be an easy way to just look at the frequency channels (using the software for your aids on the monitor at an audiologist's) and simply adjust vast swaths of them! This is kind of what I do, as I need a LOT of boosting in the lower frequencies, but for speech clarity and dynamic range of music listening, I have had to really adjust the whole GRID of frequency channels. I hope that makes sense? It definitely requires multiple visits (altho I think several here DIY at home, having bought the software and running it on their own PC) to get it just right. Persevere! There is a better fit waiting to happen with your aids (or try other brands till you find the right set).
Everyone's hearing preference is unique. Before I bought my new Oticon Opn miniRITE aids, I tried out the Widex and Resound aids. Neither one provided the sound quality I wanted (or was used to even with my 4-yr-old Agil Pros). Good luck to you!
