I feel bad for being so jealous about my sister a lot of the times

I feel like largely she just lives almost a perfect life compared to me. Like she’s prob getting married to the guy she’s been dating since high school, she has a well paying job already right out of university. And she just gets to be kinda free in a way I’m not at all. She goes out to bars and hangs out with friends and just socializes with ppl. I hate being bitter about it but I just feel so behind and like I’ll never get to live a life like that
