I share quite a bit of your psychological profile. I hate false hope. I'm like 10/10 fact-based, evidence-based kind of person. I studied math so my brain is literally trained for proving things with logic only. I don't even believe in FX-322 for myself (I have a dark, progressive, complicated, and severe form of hyperacusis that isn't noise induced).
As far as "achieving things in life before their situation began," I think you need to get outside of your own head a little bit (and I say that lovingly). You're right; you are amazingly young to have hearing problems. I feel young, but I'm a decent amount older than you. Let me share a little of my backstory so you know what I was robbed of.
High school sucked for me. I got to college and was a mess the first year. Smoked a lot of pot, drank a lot, wasn't very moral, frankly. Around sophomore year, I dropped the pot and found myself. I set out a goal (that would take from that point about 10 years) to become a math professor. I also met my (now) wife in college.
I get to grad school; my wife sacrifices by commuting far to work. I save my career by passing Ph.D. qualifying exams. Shortly after, my best friend dies unexpectedly, I developed symptoms of a systemic autoimmune disease. I was really sick. Flu-like symptoms, intense suicidal pain, fatigue, neuropathy, dryness, many other things. I spent the entire summer after my second year on a couch crying and wishing I was dead. I then had to take a semester off.
After the semester off, I was still chronically sick. I went to school, researched, took tests, taught with pain and fatigue. My "winter breaks" and "summer breaks" were massive pain flare ups after the stress of the semesters ended. This went on for about 4 years. I "managed" it with running and cutting out all sugar.
But through it all, I was successful. I was a good student in my class; my research was solid. I was going to make it. I was going to achieve my ten year goal. My wife, who had sacrificed to help put me through grad school (though I had a stipend), was going to be rewarded with a shared home; we were going to have kids.
Last year of grad school was absolutely brutal. I spent many hundreds of hours applying for jobs, typing cover letters, studying schools, practicing interview questions. I also was trying to publish my work to put me in the running for a job (market for professors sucks). I was fortunate to land a few on-site interviews for tenure-track positions. These interviews included multiple hour long presentations, meeting with deans, meeting with students, all sorts of stuff. One was two full days, no breaks. I did well.
I landed the tenure-track position I wanted. Knowing that I had a long-term position in the works, my wife and I began house hunting. On any given day, we would have to leave work and commute 3 hours (one way) to check out a home and quickly place a bid. After a number of months, we found a beautiful home (the one I am suffering in now) and got our offer accepted. The plan was to start a family in about a year.
I finish up my school year, typing my 150 page dissertation. We had to close on the house, deal with all of the pain in the ass insurance and homeowner bullshit (my wife did most of this, thankfully). My wife watched as the company she put in great work at for years refused to let her work from home to make our new living arrangement work. Regardless, she persevered and landed an amazing work-from-home job that she currently holds.
We were really going to make it. Two great jobs. An absolutely gorgeous home. A family in the future.
We finally move in. I'm not kidding you, five fucking days after we move in, my disease flares up. But instead of pain, I develop balance problems, tinnitus, and (at that point) minor hyperacusis. I'm not worried, I think it's just an ear infection or something.
I watch as it just keeps worsening and worsening. I lose my ability to converse, wear earplugs and earmuffs 24/7. I cry throughout entire car rides.
It finally got bad enough where I realized that I couldn't teach at my new job. I told my employer and we agreed to take the semester off. During that semester, I saw two upswings. I thought it was going away and that I could put it behind me. It wasn't stable enough for me to teach so we agreed to take one more semester off.
All I did was play ~40 dB music for 1-2 hours as an experiment to see what it did to my hyperacusis. That experienced dropped my LDLs by about 30 dB. I couldn't tolerate any sound. It even took me a long time to eat because I couldn't tolerate the sound of my own biting.
Finally, my employer and I meet and we (cordially under the circumstances) mutually part ways. We met through video chat (during COVID-19) and we fucking typed to each other. I lost my job through a typing conversation. (This is not any anger towards my boss, he was a really awesome guy).
Doctor finally puts me on long-term steroids. I improve by 20-25%, but level off completely. To this day, I am roughly around that level. I haven't left my house in a year. I wear earmuffs 24/7. I can't talk, can barely tolerate whispering. I was rejected disability income. My wife also had her life robbed. No kids for us anytime soon; she tiptoes around her own house. On top of providing all of the money, she has done most of the house work over the past 2 years.
I don't believe in anything. I probably have an autoimmune disorder attacking my nerves so FX-322 almost surely won't help much. Even if it was hair cells, my immune system will just kill them again. There won't be a cure for autoimmune diseases anytime soon. There won't be a regenerative medicine for nerves anytime soon (all pre-clinical). What am I living for? I'm living for the chance that it eventually gets so bad that I can't hear at all.
Trust me when I say, I know what it's like to be robbed of life.
