Anyone else here born socially awkward but later became a socially adjusted person?

I grew up EXTREMELY socially awkward and annoying, had no friends, and just felt like a weirdo and outcast everywhere I went. It's been several years since I finally overcame the problem so sometimes it's easy to forget how weird and awkward I was back then, but every time I get reminded of the things I used to do and the way I used to be, I simply cannot believe that was once me and I feel so ashamed and cringe. I feel like I'm a completely different person now with a new personality and brain and mind even though I'm obviously not. Has anyone else gone through something similar? If so, how do you feel about your old self? How are you feeling now that you've overcome it? Curious to know.
