I think you don't envy your sister but the opportunities she had and you didn't, at some point it seemed to me that you admired her.
But if you are sure that what you feel is envy, I hope it will soon turn into motivation to be better.
Maybe life was harder for you, because you are stronger than she is, think about that. @princessbusayo 😉
A great angle from you and yes, I don't need to envy but admire her and also work towards being the best in my ways.
Thanks so much for your comment and pointing it out clearly for me.
