My little sister used to be so much luckier and more successful than me all through our teens and twenties. She got married at 21, first child at 23, third child at 30, seemed very happily married, was making a living as a classical musician and live din a nice big house. All the while I took an MA, had one bungled relationship after the other, moved from country to country and thought I'd never have a family or a steady job.
I envied her life loads.
I was the wild and troublesome one and she was the successful and calm one.
Then in her early thirties she got arthritis and had to retrain to be a teacher as she couldn't play her instrument anymore, her third child has turned out to have serious problems with digestion and her oldest child became a bullying victim. Just over one year ago, she revealed she'd been having an affair and wanted to leave her husband, said she hadn't loved him for years. She's now divorced, living in a small flat with her new guy and a blended family, works as a teacher in a difficult school and has chronic pain. She is often miserable and sad and my heart bleeds for her and I worry about her so much.
Meanwhile, I now have a good job, two healthy kids and am happily married.
Two points:
Things can change very easily and are not always what they seem.
It's sooo much better to have a happy sibling you can be inspired by and proud of than a sibling in trouble you have to worry about. I now regret all the times I felt a sting of jealousy towards her. I belive my envy in a way made me a bit distanced to her. Perhaps if we would have bene closer she'd have confided in me about her unhappy marriage and things would not have turned so bad. At the very least, I would have enjoyed her happy times more with her. I sincerely regret being so small minded at the time and envying her. She didn't know, but I think maybe sometimes she sensed it.
I now feel so sorry for her and her difficult life is on my worry list.
Count yourself lucky for having a blessed sibling and instead of spending energy on envying her, ask yourself what aspects of her life you envy and try to strive to get those things too . See it as an inspiration. And if you can't aspire to those things, then look at your own life and be grateful for what you have and try to find a meaning in your own life.
