When questions like this are posted, does the OP read each one, & if so, what do you do with the info? People unload their personal issues & then what? Doesn't seem like anything happens that would help solve the problem.
I didn't develop offline social skills, because I wasn't interested. Some people thought I was being rejected & picked on, which led to my disinterest, but that's not true. I rejected 1st, & that is when I was picked on -- still happens to me as an adult. They see my disinterest in them & they decide to pick on me -- not everyone, just the adults that never developed maturity (which is a lot of people like that here in TN). I grew up mostly in FL, but don't know what it is like to live there as an adult. Have lived in TN most of my adult life. People are poorly educated, have a small town mentality (even though the population isn't that small), & most of the adults I've encountered act like teenagers. There is no incentive to interact with them.
Being alone & interacting with people online occasionally, has worked the best for me. Since I have very little experience interacting offline, I just don't have the tolerance or energy built up for those activities. It must work a part of my brain that is small, which causes fatigue -- similar to how when overweight people try to exercise, or when people try to learn a new skill, it is hard work & brains don't like to work hard. Nature prefers efficiency, so you have to have incentives in order stay motivated to work through that difficulty in learning new skills or losing weight or socializing when you don't have much experience.
