You may, simply possess attributes that are different to those, of your Brother. You are not less than him.
You are special in your own right. You are authentic, and you are wise beyond your years. You are unique.
You are introspective, insightful and creative, and you are beautiful. Those are just some of your attributes I've noticed, from my brief encounters with you, on the forum.
I used to compare myself to my sister, in some regards. My Mom taught me to write down the things I liked about myself, and the things that I thought I had done well. She would point out the ways in which I was unique to my sister and remind me/both of us, that we are just different. I do understand watching others have an easy time with things that can be tremendously challenging for us. It can be discouraging and frustrating and it can remind us of how much we do struggle with various aspects of life. Your feelings are most valid and justified.
I hope you've had a wonderful day, Starfoxx.
