AITAH because i feel jealous of my brother

I (19f) have a close cousin (21m) and there are times where i feel pretty jealous of him. I literally feel like he’s one of the gods favourite child. I mean no harm to him and don’t want anything wrong happening in his life but there are times where i can’t help but feel a tad bit envious of him. He’s tall( approx 6’2) and physically fit. He looks pretty attractive too. His family is really nice and his parents are literally the best people i know. He has a group of friends that’s stuck with him since his high school. He has a beautiful girlfriend as well and i mean not just beautiful she’s drop dead gorgeous and has a good body figure too. His family is pretty decent financially and definitely belongs to the upper middle class so money was never an issue for them. He is doing well in academics as well and has always been a school topper. He’s pursuing 2 degrees at a time and has passed every exam in first attempt. He’s not just book smart but street smart too. He goes out on trips with his friends and completely enjoys his life balancing his fun and career. He’s also religious and puts immense faith in god. All I want to say is everything in his life just looks so perfect like HOW?!! I don’t always feel jealous of him but there are times where the feeling of not having everything he has just hits me really hard. I still hope he does even more wonderful things in life and stays happy!
