i dont know how to deal with my sound sensivity

sorry for the wall of text,
I'm out of options and honestly i dont know what to do or who to seek.
i dont even know if this is a mental problem or a genetic one.
i will try to explain my situation the best i can...

i have this sound sensivity where i can't deal
with unexpected sounds they all make me anxious and panicking.. even as normal as they would sound for normal people. even a microwave popping popcorn would startle me and i would get out of kitchen to avoid that.

on stormy days i keep checking the weather radar over and over again with extreme anxiety and panic. and the same goes for new year's eve where there are fireworks, firecrackers loud car exhausts...
last year, i spent new year eve crying and panicking over firecrackers + fireworks near my place
Some dogs barks i can't also stand..

I use ear muffs and ear plugs on those occasions but its never enough, the fear is always there along with the anxiety.

I dont even know how to explain why i fear this, i just can't tolerate the sounds i used to tolerate traffic, especially motorbikes, nowadays i can't..
I've been trying to understand what would be the cause of this but i can't find an answer. i already did an hearing exam, brain exam and nothing unusual was found.

I also used to take meds for my social anxiety, escitalopram and lexapro but i stopped taking them because i got slightly better and to get rid of the side effects which made me sleepy all day.

last time i went to my psychiatrist and explained her this, she prescribed me benzodiazepine and didn't help at all.. and i only have an appointment with her again on the next year...

I dont know how am i supposed to live like this, sometimes i wish was deaf

what should i do?
