Deafness had ruined my life in the sense that it blocked so many opportunities for me.
If you've LET having hearing loss/being deaf "ruin your life", that's unfortunate.
There are very very few things that being Hoh or deaf "blocks" if people WANT to pursue that field/career/thing enough.
There are Hoh/d/Deaf: actors, architects, athletes, business owners, chefs, deans, doctors, engineers, factory workers, homemakers, janitors, lawyers, mechanics, musicians, nurses, parents, pilots, priests/pastors/clergy, principals, restaurant owners, retail workers, scholars, scientists, teachers, university professors & on & on ... the list of things that we as Hoh or d/Deaf persons CAN do is ENORMOUS, versus the very few things we "cannot do" specifically due to our hearing or deafness is VERY SMALL (commercial airline pilot, SEAL for example)
Really ... it's a matter of having goals, reaching for them and not allowing others or yourself to see hearing loss /deafness as a "barrier".
EVERYONE has "something" that can stand in their way (or they can use as an excuse for why they can't do "X" or "Y").
For example, there are things that are more difficult to do - or situations in which I face discrimination etc because I'm: female, 5'4" (not 6'), blonde, look much younger than I am, have a job that is typically a "man's job", have various rather severe medical issues - and I HAPPEN to also be Hoh/Deaf.
That being said, if *I*- or ANYONE really WANTS to do something ... 99% of the time the only thing that's REALLY standing in the way, is OURSELVES (self doubt, lack of confidence, self imposed barriers/limits etc).
Once you overcome YOURSELF - almost ANYTHING is possible... if you are dedicated, determined, passionate, innovative enough and have the internal will/need to "make it happen".
I honestly cannot think of a single way in which my being Hoh/Deaf has "blocked" what I wanted to do. I'm a musician, a college graduate (3.99 GPA), have gone back to take additional University classes, have become well respected in my career field, have been able to mentor others etc... not ONCE has be Hoh/Deaf been "the reason" I didn't do something, or wasn't able to do something I really wanted. Have I had to overcome challenges, certainly - as does EVERYONE in life. I simply do not see being Hoh/Deaf as a "problem", or as "limiting" - if I truly WANT to learn something, do something, achieve something - then I find a way to make it happen... if it doesn't happen, I don't "blame it on being Hoh/Deaf", rather I look at what was the hindrance/barrier and then work to address it via accessibility, education, awareness, focus/desire/need to make it happen etc.
If Deafness "ruined your life" - it's only because you let it... YOU have to decide that you CAN do what you want, be what you want etc.
