Is it bad that I feel jealous of a friend I taught how to write? (vent)

I really need to get this off my chest. I’ve been into writing for a while, and recently, I taught a friend who became interested in it the ropes: how to post, which platforms to use, and even some writing tips. But now, they’ve actually become better than me, and their work is getting way more attention. I know it’s not their fault for being talented, and i should probably be proud but I can’t help feeling hella jealous and insecure. It’s reaching a point where I’m honestly considering quitting because I feel like I’ll never be good enough...

P.S. Please don't ask for the links to our works! I’d like to keep everything anonymous to protect our privacy, plus I'm not really looking for a comparison lol. I just needed to let this out
