How to stop being jealous of things my girlfriend has done?

I love my girlfriend and she loves me but I just hate feeling so jealous about her she has friends she goes out with and been successful at achieving a skilled career, and honestly she's always been successful even through her high school years where as compared to me I feel like I just don't bring anything to the table like she does, I never had many friends outside of school, I never had a passion for achieving a successful job, and never had any accomplishments like she has which I guess hate to say it is probably because I always been depressed without realizing I was.. I just didn't think it would honestly put me so far behind but yeah it does im honestly just a loser who works at walmart and no plan for finding a better life or a better job mostly because I just don't think I'd qualify
