Im sick of being so jealous of my sister please give me an advice about this.?

So im 17 & My sister is now 20 years old , & My sister always gets attention everywhere she goes , She went to vegas not long ago & Paris Hilton ex boyfriend came up to her & started dancing with her. & This guy who owns most of the clubs in vegas got her in for free , & When she was at the club all the guys were like "take a picture with us your gorgeous" like Every guy approaches to her & asks for her number! , it just sucks because guys never go up to me & im pretty too , But my sister looks more sexy i guess! , im just jealous because shes popular , shes living the life i wish i lived by going out alot with her friends , Because im always home i never go out... my friends are flakes & im homeschooled btw. but yeah my sister always have such hot guys coming up to her! & i just never have any guy come up to me. idk whats wrong with me? But im sick of being so jealous of her & her life style. how can i stop being so jealous! Like i can go on about this! but please give me an advice ..Thank You<3
