Look Shadix, I was 29 when I went back to school. I am excelling. And unlike you, a therapist did suggest to me it was worth it to test me for (high functional) autism and I was in complete social isolation where the only social interactions I experienced was with my parents, who have an extremely unpleasant hateful relationship

I am excelling. I even got the most amazing girl in my classes to become interested in me in some manner.

Your problem, and my problem in the past was, that I had no goal and ambition. Because I had no drive. Because I only wanted to try if I was sure I would excel. My idea was that if you do not try, you cannot fail and nothing is lost. And if you can accept a life filled with emptiness, you are more happy and content then when you have an exciting life, but you yearn for more.

Also, you don't need to be witty and quick of mind to flirt with a woman.

My best friend (who I haven't met in person for 6 years) told of a similar story to yours. He thinks him and me are alike. So maybe he and you are alike in some manner as well. He admired his brother for his looks, social skills and interactions with woman. Later on, he got closer to his brother and he learned that his brother admired many things my friend had, but his brother had not. And they got a better friendship realising this. At least that's what he told me.

Yes, you cannot beat your bother at what he does best. And yes, people gravitate to strangers that are charismatic. If people also prefer that charismatic person as a friend, I am not sure about. Maybe, but the effect will be less.

What do you really want out of all of this? You to tell us how many negative thoughts you have about yourself and everyone else to tell you that you are wrong and that you are charismatic and witty?
Do you want to know that there are people who share similar experienced?

Look, your concerns are understandable and many people, especially males, have to struggle with this (as females are generally valued slightly different). But what are you going to do about it? Like I think I have said before, given what you have said, you either accept yourself, change yourself, or a mix/compromise of both. And what are you going to do, from tomorrow onwards, to achieve this?
