how to stop comparing myself to others

I would like to know how. It seems to come naturally for me, but i know i'll never be successful or happy if i keep doing it. i'm constantly comparing my life to others, and i feel like a total loser compared to people who are successful. I'm 21, don't have a job (and never have), am just starting 2 year college now, and have never had a relationship. i would like to stop focusing on all of the ways i'm behind in life so i can actually get somewhere in life and not be so depressed, but my mind keeps nagging me. how can i start thinking a little more positively?

Maybe try and see it as the grass isn’t always greener on the other side. College is great and you should be really proud of going especially with social anxiety. It’s always possible to form a relationship in college, give yourself time and keep trying your best. After college maybe you could get a good job. Just try and focus on your goals and how you’re doing, not what others your age around you are doing. I know it’s easier said than done, I compare myself to others everyday but I try hard not to because it makes me feel awful. I am grateful for what things I have accomplished.

actually, i'm going to do college online
