I (f21) am jealous of my twin sister (f21)

My sister and I are fraternal twins which means that we don’t look alike.

We did pretty much the same things at school and we go to the same uni but about a year ago she got a sugar daddy and her life has been completely different. She has a nice apartment in the city and she’s been travelling and I feel crazy and bitter that she gets to do all these things bc she’s prettier than me

Recently she wanted to start a business and her sugar daddy introduced her to some people who want to invest. I know I’m supposed to be happy for her and she’s never thrown it in my face or anything but when I have to bust my ass to get anything I want and I see how she can just float through life it just makes me feel so mad.

I love my sister and I love that she’s succeeding and happy but I don’t know how to stop being bitter about it. I don’t want to ruin my relationship with her bc lately I feel like I’ve been really snarky and rude and I don’t want to be like that. How do I stop being angry at her? Does anyone have any advice on how to not feel bitter about all this?
