@JoshuaD2002 Right now you're experiencing a lot of anxiety. Some of the advice you're receiving here (It's too soon to worry; Try to relax) is good and true advice, but it probably sounds impossible. I totally get it. I experience A LOT of anxiety and I know you can't just turn it off. But I've learned that if you work at it, you can tone it down.
I don't want you to think too much about the future. Maybe your tinnitus will go away. That would be great. But you still have to get through today. I find that with my anxiety, the best thing I can do is to distract myself from my worries. It's not easy. That's why I say it needs to be "worked" at.
Find some task that doesn't take a lot of thought, but does keep you busy. Perhaps you can find some household chore (tidy your room, sweep the floor, any chore that isn't noisy). Busy-work is good for using up nervous energy. Also find some entertainment that might distract you. Do you have a favorite movie or game or hobby? Don't expect fun. This is work too. Your goal is distraction. Do one thing today to distract yourself.
And remember that you don't have to do this alone. Come here and tell us about your favorite hobby or movie or whatever it is that you like. It's good to talk about ordinary things, even if your heart isn't in it. It's good for you like a vitamin is good for you: you don't feel the effects right away, but it's doing its job.
