There are a lot of topics about how to deal with your own envy... but what do you do with an envy of others? 
As for me... Fortunately, I face envious to my art/writing not often (yet?!), obviously because of my inexperience in it.
But even these rare occasions worry me, because they can potentially turn into the source of problems in the future. In some other areas of life it already bothers me a lot and caused me some problems. 
I mean, I certainly enjoy, when people admit my achievements and give me their respect (who don't enjoy it?
). But when they are envy, it bothers me and sometimes even makes me feel guilty. It's especially sad, when your friends drift away from you just because they don't feel comfortable with you because of their envy, while you still want to hang out with them.
If only I knew what can I do...
I feel like I can't do much with the feelings of others.
But if anyone has an advice, you are welcome.
UPD [after several posts]: I certainly understand that people, who make you feel bad intentionally because of their envy and don't want to struggle with these feelings, don't worth your worry, and it will be even better if they leave your life. My question is more about those buddies, who aren't monosemantic toxic, understand destructiveness of this feeling and don't seems to make you feel bad voluntary, but want to change.
And of course I understand that envy of others is not a reason to stop what you are doing. And that it shouldn't be a reason of your guilt (but sometimes it is, involuntary).
