I totally get what you mean. I'm 34 and have had severe hearing loss at least the past few years, and at least mild hearing loss since a teen. I just received two hearing aids earlier this year, as it's in both ears. I find that the aids don't really work well for me though; I have to be in a quiet place with the volume turned up most of the time to hear people. I try to read lips. I don't know if it's the meds I'm on making my brain slow or what, but I can't read lips anymore. I am still barely getting by even with two hearing aids. In fact I've stopped wearing them unless I'm in meetings or groups and need to hear.
It's difficult to accept. I have moments of utter torment and anguish about it. I'm not deaf, but I can't hear. I can't converse with my friends, most jobs (even if I could work) are out for me because I cannot interact with customers or even other employees and employers. It's isolating and kind of depressing. But my partner (who has hearing loss in one ear, since birth) and I are going to take ASL together in the winter, so that we can begin to communicate better with each other, as we cannot understand each other either. And then maybe I can get a job in a deaf environment.
I don't know what to tell you. Things just happen to people and there's no sense in most of it, I tend to agree. Do you have any deaf or hard of hearing friends? Have you considered checking out events in the deaf and hard of hearing community where you live? It will probably help to at least be talking to and hopefully hanging out with people who understand. I know that a lot of people get impatient with me because I can't hear them. Even after 5,6,7 times of repeating themselves.
You are also welcome to talk to me, anytime you like, if you need help coming to terms with stuff, or just want another friend who has hearing loss and knows what it's like.
