advice?

when i was in 6th grade i became friends with this artist who was fairly the same age as me, and i really liked her art to the point where it became obsessive. i didnt do anything weird but it slowly started ruining my perception of my own art because i compared myself so much to her and since she was growing really quickly at the time online i started envying her popularity too. (like id get jealous of her friendgroup and friends and everything ab her) i decided to cut her off because what was happening to me was unhealthy but 4 years later i still think ab her and look at her art acc (still active) when i can and still genuinely believe its signifcantly better than mine. im more secure about myself and my art since then but now i have still no idea why im so obsessed with her

anyways thats it how do i forget about them and everything pls
