One example/experience is not a valid sample for any social scientist or singer. My advice is find a good voice teacher. I am amazed that at the progress even I have made by taking lessons. I was depressed initially by all the things I did wrong, most of which I did not even realize. But one by one they get fixed and the voice gets stronger and purer and more confident. I was over fifty when I started so there is hope for everyone. And be sure there are people who share your taste in songs and music. Keep at it. Singing is as fine a way of seeking the meaning of life as there is.
