@Flower88Hello, I am so sorry to hear about your situation.
I wanted to share some of my experiences, knowing they will not be the same as yours, but hoping they may offer some suggestion you might not have yet thought of to help you deal with your situation. I hope I do not offend and hope you find some moments of respite from the awfuls of the situation soon. If I have it wrong I apologise in advance.
About three years ago I was diagnosed with vestibular disorder, probably due to a virus. It's a most disconcerting situation, and while mine is/was different from yours, I can empathise with both the dizzyness and the anxiety issues. I already had major anxiety issues and this just added to them even though I have an anti anxiety medication that I use when needed.
A new gp after consulting with my pharmacist, prescribed me some meds for the dizzyness and nausea, which have worked wonders for me meaning I could move more often and with greater agility without the debilitating effects usually exhibited.
More recently I began using a silcone type of ear plug to block sound and that has been a great boon as well, affecting remissions of the near constant tinnitus as well.
Ear care is of utmost importance to me keeping my balance and reducing the symptoms. You may know about ear care and how water/ hair care products can aggravate balance conditions, although this might not be relevant to your situation.
To combat the loss of balance potentials, I learned to walk sofly, slowly and with great care and to turn slowly so as not to set it off. It has settled significantly in the last little while.
In short, I relearned how to move and also to avoid anything that sets it off, like flashing lights, too much brightness, and other things. Yours will be different I'm sure. What I'm trying to suggest is that there might be small things you have not yet thought of that can be slowly changed over time to help accomodate these symptoms and help make your life a little more pleasant.
Start small, leave the dating for a time somewhere in the future, others here have made some excellent suggestions also.
Hopefully you will find a way to accomodate these symptoms and find there can be pleasant moments in your day.
