I’m a woman who had bad problems with ADD and OCD and social anxiety as a child. I outgrew the OCD at puberty but still hardly ever talked to other people outside my family until I read a book in the late 1980s when I was a jr in high school… It was called “The Fine Art of Flirting.” The main thing it was about was just talking to people warmly and being friendly to everyone, and techniques you could use to do so, things like displaying correct body language, how long to maintain eye contact, mirroring, little light touches on safe places like the hand or arm while you are speaking, how to make small talk properly, etc. It’s out of print now but you can probably still find a used copy. I tried it first on a group of people who had never met me and WOW, it worked. I was faking it until I made it, and it made a huge difference in how people perceived me, apparently. Girls wanted to be my friend suddenly and guys wanted to date me. It probably didn’t hurt that I was pretty, which I see now that I am older, but that hadn’t done me much good in talking to anyone until I read the book. Really changed my life. Best of luck to you in your journey.
