Everyone's tinnitus is unique to them. Tinnitus is like a fingerprint, no two exactly alike. You and I share a portion of the same symptoms, but not all of them. When my tinnitus first struck me, I too did not know how I was going to continue. I was in a state of disbelief. Of all the things that feared happening to me, this was not one of them.
It's been almost two years now and I do notice a lot of things that tell me I am habituating at least a little bit. My tinnitus is extremely reactive. Noises that I encounter during the day are often like pouring gasoline on my tinnitus (a hissing/static noise). At first I could not tolerate going into any kind of store, coffee shop, etc; without inserting ear plugs in my one good ear. BTW, I completely lost all my hearing in right ear at same time the tinnitus struck. Anyway, I can now shop without the need for an earplug, but if I'm sitting in a coffee shop I still often need them. Small steps.
A couple of tips that helped me, but may not be helpful to you. Everyone is different, so it's good to experiment with some different formulas that others are doing to see if you may get a little help living with this scourge. Watching TV was pretty unbearable to me when the tinnitus hit me. Through trial and error I found that using a noise canceling Bluetooth headset allows me to watch TV with much less discomfort than without. I'm not sure why it helps, but it does. I also use those noise canceling Apple ear buds that have become popular. I don't listen to music or TV through them, but just utilize the noise canceling feature when I am in a room with people talking. They seem to take the edge off of the tinnitus and make it more tolerable. It's like installing shock absorbers for your ears/tinnitus.
There is no great "fix" out there for everyone. You can gain a lot of info reading through the stories in here and maybe you will learn some techniques that will help your own case. I have fully excepted that this is with me to stay and am not expecting it to ever go away. But I think I have gotten to a point through utilizing some techniques that I described, habituation (time and acceptance), and my faith (important to me in any human challenge) I have reached a point where I know I can go on and know that this is not going to destroy me. That in itself is a huge mountain to get over, where you realize that... "Okay, I can do this".
