When I started out with this condition, I wished it was life threatening: having the torture end by simply being removed from existence seemed like a heavenly blessing. Not meant as negative criticism, but the "it's not life threatening, stop worrying" statements felt like a bad excuse to me to just end the discussion. I was not afraid to die, I was afraid to keep living like this. Being only 32 years old, it felt like my wonderful life ended just when I had started to build it up.
That was half a year ago, and my perspective has changed a lot now. Though I still find the sounds annoying at times, I found out that heading out and finding new (or old) things to do that I enjoy, over time it made me value my life again.
@all to gain
In that way, I agree with John: no one else can pick you up, you have to find a way to start enjoying life again by yourself (although other can of course support you in doing so). Find something, new or old, that you like to do. Starting to do so is the hardest part, but as days progress, you will notice you get used to the new tasks that are part of your chosen activity, and you will start enjoying them more. In my case, I used something simple that helped me to go outside again at the same time (Pokemon Go).
Not at all saying that this is easy to do: it will feel like trying to move a mountain at first. But trust that you have the capabilities to do so. You are unique as an individual, but you are also a human being, and as history pointed out plenty of times, humans have outstanding abilities where it comes to adaptation to new situations.
