Only like 2 of my friends are art students, and I do see them making fun of bad art from time to time. One of them can draw/paint very well, and one of them sucks ass. But to be honest, when they make fun of art, it's more like they already hate the person and they are just finding more reasons to hate them.

It's uncomfortable when they get like that, but OP, honestly if the chance of getting made fun of is scarier to you than having fun drawing a picture, then just save yourself from the high blood pressure problems and don't draw. Honestly, most people won't give you shit if you draw badly unless you're an obnoxious person, which you don't sound like.
