I assume you mean "what did I do to get better."
I think what has helped me the most was finding a community of people who I could trust and who accepted me for who I am. My SA was much worse before I became a Unitarian Universalist. After joining such a welcoming community, I felt much more comfortable being myself, which helped me feel comfortable in other settings.
Also what has helped was making a list of things I didn't like about my personality or the way I handled social situations and finding ways to get over each one by one. This was the part that took a long time, but it was very worth it! I felt so much better each time I crossed something off the list.
Feel free to message me if you would like to know more. I'm happy to help in whatever way I can.
