Welcome to the forum
@KarinaK. Perhaps read up on glynis's response above or message her to get support from her as she has dealt with Meniere's and may have some personal insights to give you. For the vertigo, this exercise created by a lady MD has helped me but may or may not help you with your type of vertigo from Meniere's. I did the exercise twice and it healed my BBPV type of vertigo. It never hurts to try it. Here is the link:
As far as the T part, the more anxious, stressful and depressed we are, the more T can flare up. If our brain thinks T is a major threat, then all our senses will be zooming on it and it will be perceived a lot louder and more intrusive. So we need to try our best effort to stay calm and positive. Try do some relaxing exercises, activities or hobbies.
For diet or life style, try to take some natural supplements that will help calm the nerves, such as Lemon Balm, Valerian, Hops, Catnips, Passion Flower, Chamomile, Lavender, Kava, Melatonin etc. You can google search or check Amazon.com for each of them to know how people review these products, and see if you can take them as a supplement. Also check out this site on using natural herbs for helping to sleep or to calm the nerves.

For supplement or diet, members here often recommend some good supplements, such as NAC, Magnesium, Zinc, B12, D3, etc. It is advisable to reduce intake of salt, sugar, MSG, caffeine, alcohol etc. or to switch to more healthy diet. Of course prudence is needed here as you still need to enjoy life and your T may not be affected by these things.
Try to read up the success stories to give you some hope and comfort that given time and with a good strategy (such as CBT, TRT, mindfulness etc.), that you will get better like those who wrote the success stories. I used to suffered from ultra high pitch T and severe hyperacusis and was in a mess. But today I live a normal, productive and absolutely enjoyable life. I posted my success story. If you have the time, check it out. Take good care. God bless.
