Galaxy1012,
Your life may seem at the end but it's not. I've hit the bottom many times and it does eventually alleviate.
I highly suggest a neuropsychologist! This doctor knows all about the brain and can help you with understanding your injury, emotional problems, anxiety, and offer strategies to help you.
For the tinnitus which is frustrating I run a fan (photo included of what I use). It makes an even sound, not fluctuations, and does not light up my hyperacusis. It masks my ringing nicely.
You sound very depressed. Keep a journal of your moods if you can and whether you think your meds are working. Keep appts with psychiatrist to work out best med and dosage. Possibly something for anxiety too.
Keep reading on the forum and try to participate. You will come to realize that you aren't alone and there are many people to relate to.
Make a list of what helps with your anxiety and use it. Find an activity to do that you enjoy that doesn't push your symptoms into misery.
I'm coming off of a 'this really sucks &$@!%# and I'm in a dark place' bender. It's a horrific episode. Not having control of my emotions let alone a lot of my life is horrible but the fear of not being in control makes it worse.
These times do pass. Reach out. Hold on. You will make it through.
