Going through 50 years of life in total silence one would think that would be totally miserable and very hard to adjust to daily living.
Here are just some things I had to do a bit differently growing up. And no my life was far from miserable.
As a very young child/toddler there were no bed time stories read to or a musical mobile hanging over my crib because at that really early age of life I did not understand ASL and also when I was very young my mom was just learning it as well. So things she did to help me relax and put me to sleep were with other senses. Calming photos, touching soft things like soft stuffed toys, certain smells that would help me relax.
As I became older and started learning sign language, I also wanted to watch TV like other kids did. Well that was not as easy for me to do. I had to also learn how to read words a lot quicker than most kids because that is how I got my sound from the TV. From the closed captions. Shows like Sesame Street, Mister Rogers, Electric Company became my friends.
Even older in life and a huge challenge for me was learning to drive. Many people today even ask how deaf people can drive a car. Well of course there is no problem with our legs or arms or eyes it is our ears. So many ask what about when an emergency vehicle is coming. How do I know. I have to really rely while driving on my sense of sight. Like double time rely on it. Not only the normal like what the traffic is doing around me, but also my eyes are my ears as well. So if I see flashing lights I will as soon as I can move into another lane and get out of the way. When I am driving I am always checking my mirrors for things going on around me. I also have no distractions going on while driving. There is no sense for me to turn on the radio unless I turn it up so loud that it vibrates the entire car so I can feel the vibrations. I think people around me would think I was totally nuts then.

You also think texting while driving is dangerous and yes it is, but having a conversation with a passenger while using sign language is even worse.

Don't ever try it. In the time I have been driving I have only gotten one ticket and that was a parking ticket.
As I have gotten older and been raising a kid on my own, I have had to use different methods to waking up. An alarm clock does not work for me. So I have a device that straps to my wrist before I go to bed and I set it just like an alarm clock. When it goes off in the morning it vibrates like crazy to the point where my arm starts shaking. It wakes me up. This is a very good thing when you have a teenager who is very capable of hearing an alarm clock, but still sleeps through it because she stays up way too late on a school night and don't want to wake up early in the morning for school.
As you also are probably aware the technology of phones have gone crazy over the years. For me they are pretty useless. I can't converse on a phone like a regular person. I do use the texting which is great. These Zoom things and FaceTime gadgets don't work for me as well mostly because it is very difficult to read the lips of the person/people on the video and especially if there are multiple people on the Zoom call and the conversation is moving around from person to person making it impossible for me to read the lips.
As you can see these are just a few of the things in my life that I have had to adjust to , but certainly not enough to make it a miserable life for me.
