Went through your thread and I can sympathize. You'll be able to pull through this. I've been dealing with my own HA issues - I have this constellation of somewhat unrelated symptoms (or sensations) and my brain keeps going to the worst case scenario for all of them. I made a thread that got very few responses (my post was miles long, I guess people don't like reading novels lol). Your journey is very well documented and is a great read for HA sufferers. Since you post what is going through your mind it helps those of us relate to you, and even though this is an online space I'm hoping you don't feel alone in what you're dealing with.

Stay strong.
