Is being jealous of talent normal?

I like drawing. I draw all the time. I study human anatomy to help make my drawings more realistic. And I get complements for my drawings too. I've learned to deal with hate about my drawings all the time. But my emotions suck sometimes.

See, I have a friend (let's call her L) who loves my drawings. I draw her pictures of BTS for her since we're both A.R.M.Y.s. I have another friend (let's call her M) who goes to a PVA school for drawing and is popular and pretty (blonde hair blue eyes pretty)

One day, me and L were hanging out after class and I got a Snapchat from M. It was just a streaks snap, but for her streaks she used a drawing she did of a profile view of a woman. L looked over my shoulder as I was looking at the drawing, already jealous of her talent. I would've tried out for PVA, but my mom wouldn't let me because she doesn't like the idea of giving kids the image of being so special that they go to a completely different place than "average" kids.

L suddenly shouted in my ear, "Wow that's really good!" She couldn't see my face, but I was frowning because I was so jealous at that point. I told her, "Yeah, she goes to PVA for art." And then L just laughed and said "Yeah, I'd accept her too!"

That was a couple days ago.

Now L talks about how M's art is really good and she wants to meet M so that M could draw her stuff. I was actually hurt by that. I felt touched that my friend wanted me to draw her things, but she doesn't anymore. L even followed M on instagram and talked about how she was so talented at taekwondo (a sport both me and M do, and M's better than me at that too) and how M is pretty and popular.

I'm so jealous of her but M is so nice that it pains me to be jealous. Ugh I hate it so much...
