Anyone have “successful” siblings ?

Anyone have siblings who are doing well? Does anyone have siblings that are essentially polar opposites of you? My sister is everything that I’m not and it makes me so upset. Shes making great money, she’s smart, she’s pretty, you know name it. She quite literally won the generic lottery from a looks, personality, and intelligence standpoint. And then there’s me.. the Low IQ, Autistic, ugly retard whose sole purpose is to sit here and play the same game over and over as I slowly rot in my room. I genuinely can’t believe we come from the same parents. I have a deep sense of envy that has taken over me because I just can’t fathom how unfair everything is .
